Explore how triple tempered tool steel may reduce punch fractures, with custom punches, dies and blades from Gunna Engineering in Melbourne.

Tooling failures cause severe financial losses when production lines stop unexpectedly. Repetitive mechanical stress disrupts manufacturing schedules and increases maintenance costs for commercial facilities in Melbourne. Utilising triple tempered tool steel components may reduce avoidable failure when the grade, geometry and heat-treatment specification suit the application.

Stamping Punch Fractures: Eliminating Brittle Tool Failures

Heavy-duty stamping punches require a precise balance between structural hardness and impact toughness. Where appropriate, a specified tempering cycle can help balance hardness and toughness for repetitive press work.

Continuous high-speed press runs accelerate mechanical fatigue on poorly processed metal stock. Eliminating foundational material weaknesses ensures that production tools maintain consistent stamping performance without premature chipping.

Mitigating High Volume Production Risks with Press Tooling Stress

Operational stress shortens standard tool life. Selecting premium materials reduces sudden mechanical failures during demanding production runs:

• Accelerated production velocities: High-speed mechanical press lines subject standard punches to extreme cyclical stress that triggers rapid structural shattering.
• Varied material thicknesses: Heavy-gauge metal sheets demand exceptional punch toughness to clean-shear tough blanks without suffering premature edge chipping.
• Complex component geometries: Intricate stamp profiles create severe localised stress concentration points highly prone to rapid mechanical fatigue failure.
• Abrasive stock materials: High-tensile structural alloys accelerate deep abrasive surface wear and induce premature micro-structural degradation during operation.
• Thermal expansion variables: Continuous friction generates extreme localised heat buildup that alters foundational metal hardness and compromises dimensional tolerances.

Optimising Thermal Processing Standards with Triple Tempered Tool Steel

Industrial tooling requires specialised thermal processing to eliminate internal material flaws. Our engineering team monitors operational data trends to address the evolving cost pressures highlighted across the Australian Industry Group Manufacturing Performance Report.

Punches and dies used in demanding industrial applications require materials that maintain stability under repeated mechanical impact. Triple tempering tool steel supports this requirement by improving component stability and helping produce a tighter grain structure during heat treatment. These characteristics make the material suitable for tooling that must perform consistently across high-load punching operations.

Material Stability for Repeated Punching Performance

High-impact punching places significant stress on tooling components during daily production cycles. Triple tempering tool steel helps address this challenge because the heat-treatment process stabilises the steel structure and improves resistance to repeated mechanical load.

At Gunna Engineering, we manufacture punches, dies, and blades using CNC machinery that allows tighter control over dimensions and tolerances. Our tooling undergoes heat treatment in a vacuum furnace followed by triple tempering to produce a more stable component with a tighter grain structure suited to repeated punching applications.

Why Material and Process Matter in Punches and Dies

Punching tools perform reliably when machining precision, material quality, and heat treatment work together. Several practical manufacturing considerations influence the long-term durability of punches and dies.

Important considerations include:

• Stable Component Structure: Vacuum furnace heat treatment followed by triple tempering helps stabilise the steel structure, which supports predictable behaviour during repeated punching operations.

• Tighter Grain Structure: A refined grain structure contributes to improved material consistency, helping punches and dies perform more evenly during high-impact production cycles.

• Accurate CNC Machining: Precision machining helps maintain correct tolerances and alignment so punches and dies fit properly within punching or shearing equipment.

• Versatile Tooling Shapes: Punches can be produced in round, oblong, square, hex, or custom profiles, allowing tooling to match the requirements of different machines and production tasks.

• Compatibility with Older Machines: Replacement punches and dies can be manufactured for legacy punch and shear machines, allowing businesses to maintain equipment that remains operational in many workshops.

High-volume metal fabrication needs machinery that offers extreme precision and minimal downtime. The performance of the guillotine or press depends directly on blade quality, making the selection of the proper shear blade steel a critical engineering decision. Manufacturing efficiency, material compatibility, and long-term maintenance costs are all determined by the chosen metallurgical composition.

Metallurgical Requirements for Shear Blade Steel

Continuous, heavy-duty production cycles place immense stress on cutting tools. This demands materials that expertly balance both toughness and hardness for sustained, high-volume throughput. Engineers must analyse mechanical properties to ensure the chosen shear blade steel delivers an extended service life between necessary maintenance cycles.

Optimal blade performance also relies on excellent fracture and chip resistance. This is a crucial measure of resilience against sudden, high-impact loads and material irregularities. The steel must exhibit deep hardenability during heat treatment with optimised impact toughness to prevent catastrophic failure in demanding production environments.

Comparing High-Performance Steel Alloys

The industry relies heavily on tool steels like D2 and H13 for demanding shearing tasks. D2 tool steel, a high-carbon, high-chromium formulation, provides exceptional resistance to abrasive wear due to its high volume of primary carbides. This inherent hardness ensures the cutting-edge profile is maintained when processing high-strength alloys, which minimises the frequency of regrinding.

H13 hot-work steel is specifically engineered for thermal resilience. It retains vital strength and toughness when operational temperatures climb past 300°C, making it the definitive option for hot shearing applications. This specific composition provides superior thermal durability without the inherent brittleness sometimes associated with ultra-hard cold-work steels.

Factors Affecting Blade Longevity

Maximising blade longevity requires careful consideration of machine parameters alongside the selected material composition. The highest quality shear blade steel can experience premature failure when operational best practices are not consistently applied.

Attention to the following operational factors is critical:

• Optimal Rake Angle: Adjusting the angle of the top blade minimises instantaneous shock load, ensuring the cutting force is distributed progressively across the material.

• Precise Blade Clearance: Correct spacing between blades ensures a clean, square cut and prevents secondary damage like burring or material deformation.

• Material Hardness: Cutting material that exceeds blade capacity accelerates wear, requiring a more robust alloy or significantly reduced production speed.

• Proper Lubrication: Applying cutting lubricants reduces frictional heat and chip adhesion, which preserves edge sharpness and slows down abrasive dulling.

• Regrinding Schedule: Adhering to a defined schedule removes minimal material before dulling occurs, sustaining blade geometry and extending serviceable life.

To date, numerous end products maximise CNC machined metal parts. Some of these products are fittings, housings, brackets, rollers, and suspension arms. But before these products can be fabricated, most of the CNC machined metal parts still have to undergo various heat treatment processes. Heat treatment processes are intended to make metals more workable once they will be fabricated and manufactured into different products. They also help improve the properties of metal parts.

Heat treatment processes that can be used for CNC machined metal parts are as follows:

Annealing

Annealing is a heat treatment process that can change the physical or chemical properties of a metal part. Some of the changes that can be obtained out of annealing include reduced hardness and increased ductility. This process is done by heating a CNC machined part to a critical temperature, maintaining the temperature for a specific amount of time, and air cooling the metal part slowly.

Case Hardening

Case hardening is another heat treatment process that involves the hardening of a part’s surface without altering its underneath metal layer. A thin exterior layer of harder metal is known to develop to CNC machined metal parts that undergo case hardening. Metal parts that are made from iron and steel have low carbon content. And with the application of heat and carbon-rich substance to their surfaces, they can easily obtain a durable, wear-resistant outer layer that can be useful for different applications.

Quenching and Tempering

Quenching and tampering are two-part heat treatment process that can increase the hardness of CNC machined steel parts. During the quenching process, a specific part is subjected to a high temperature, causing the crystalline structure of the part to change from being ferrite to austenite. Afterwards, the quenched part is cooled rapidly to effectively secure the phase change.

Tempering, alternatively, is done to heat quenched metal parts to high temperatures. The heat out of the tempering process is intended to reduce the brittleness of the material and improve its strength.

Stress Relieving

CNC machined metal parts are often subjected to stress, which can compromise their quality as they are further processed. Fortunately, stress-relieving can easily preserve the overall quality of these metal parts. Stress-relieving involves the heating of these metal parts to high temperatures and consequently cooling them slowly. This process, however, is only applied to remove residual stresses, helping the parts obtain huge improvements over their mechanical properties.

Precipitation Hardening

Precipitation hardening is somehow similar to quenching and tempering with some additional steps. Under precipitation hardening, the metal part is heated to a high temperature, quenched, and then heated again to a much lower temperature. As the part is heated to a low temperature, the precipitates in the alloy are dispersed. Additionally, the irregular movement within the microstructure is reduced, helping the part obtain increased strength and hardness.

To know more about heat treatment processes, you can contact us at Gunna Engineering.

Not all tool steels are created equal. Tool steels can be classified into various grades, with some of them boasting increased resistance to corrosion and damages due to the presence of certain elements. Some common elements that are present in tool steels are tungsten, chromium, vanadium, and molybdenum.

If you are choosing a suitable tool steel grade for your specific application, the following are some important things that you must thoroughly consider.

Shock and Impact

Some types of tool steels tend to be hard and brittle, which makes them susceptible to fractures once they encounter large impacts. Fortunately, shock-resisting tool steels have a commendable degree of toughness that allows them to withstand shock and impact. One drawback of this type of tool steels, however, is that their overall hardness and wear resistance are slightly diminished. And so, shock-resisting tool steels must only be used for tools that are expected to face large, sudden impacts on their daily applications. Chisels, shears, and hammers can be produced out of shock-resisting tool steels.

High Temperatures

Another thing to consider in choosing the appropriate tool steel grade is the exposure of the tool to high temperatures. You see, most tool steels undergo heat-treatment processes. If ever tool steels are reheated again, then their hardness and wear resistance may deteriorate as it counters the previous heat-treatment process. For high-temperature applications, you must choose hot-work tool steels as they do not lose core valuable properties even if they are exposed to elevated temperatures. Hot-work tool steels are suitable for making casting dies and hot shear knives.

Low Temperatures

Low-temperature applications can also affect the overall properties of a tool. And so, your tool must be made from cold-work tool steels so that they can effectively withstand the damaging effects of low temperatures. This tool steel grade has an increased amount of chromium, manganese, and molybdenum, which saves it from undergoing a rapid quenching process. While the presence of these alloying elements makes cold-work tool steels more expensive than others, they still help these tool steels to achieve good mechanical properties. Cold-work steels are great for punches, dies, and gages.

High-Speed Levels

There are several tools that will be utilised under fast movement and operation. And with the wrong tool steel grade, you can expect your tool to gain decreased hardness and wear resistance. Additionally, your tool would wear quickly as soon as it is used in high-speed applications. To prevent these situations from happening to your tools, you must fabricate them with high-speed tool steels since they possess high wear resistance and resistance to high temperatures. High-speed tool steels can be used in making drill bits, pump components, and cutting blades.

Choosing a tool steel grade for your set of tools must be generally based on these elements. If you need help with fabricating tools, feel free to contact us at Gunna Engineering.

The post Things to Consider When Choosing a Tool Steel Grade first appeared on Gunna Engineering.

One specific type of steel that is used in making tools is a tool steel. Tool steels are carbon and alloy steels that are extremely popular for their hardness, abrasion resistance, and deformation resistance. They are also known for their ability to withstand extreme temperatures and heavy loads.

Properties of Tool Steel

As mentioned, tool steels are carbon and alloy steels that are intended to be used for manufacturing tools such as cutters, reamers, bits, and others. The resistance of tools steels against abrasion, deformation, and extreme temperatures is brought by the presence of carbide formers like chromium, molybdenum, tungsten, or vanadium. Cobalt or nickel elements also help tool steels attain their enhanced properties.

The ability of tool steels to withstand high temperatures allows them to be shaped into a diverse range of tools. They can even come in soft or annealed condition that makes them convertible into different types of products. In manufacturing tool steels, they are typically melted in furnaces and subsequently processed into tools and components. They can likewise undergo further heat treatment after being fabricated and converted into a tool.

Types and Applications

Tool steels can be grouped into three basic categories, namely cold work tool steels, hot work tool steel, and high-speed tool steels. The following, however, are some of the most popular tool steel grades that are used in different industries today.

• Air Hardening: Part of the cold work tool steels is air hardening tool steels. Their high chromium content allows them to possess low distortion factor during heat treatment. They also have great machinability and can effectively balance wear resistance and overall durability. Air hardening tool steels can be used in producing blanking, die bending, embossing, gages, knives, and lamination.
• Water Hardening: Compared to other tool steels, water hardening tool steels are much more brittle. Even though they can retain high hardness, this type of tool steels cannot be utilised in high-temperature applications. Instances of warping and cracking may be visible since they must be water quenched. Water hardening tool steels are used to make cutting tools, knives, reamers, and cutlery.
• D Type: D type tool steels are also part of the cold work tool steels. They are primarily composed of high carbon and high chromium, which help them obtain great abrasion resistance and other properties of air hardening tool steels. D type tool steels are used in fabricating burnishing tools, coining, cold forming, forging dies, knurling tools, knives, rotary slitters, and many more.
• Hot Working:One primary classification of tool steels is the hot work tool steels. This group of tool steels is best known for its cutting ability under high temperatures. The inclusion of additional alloys allows them to work in applications that have elevated temperatures. Some applications of hot work tool steels are casting dies, hot forging, hot shear knives, hot swaging, and hot trimming.
• Shock Resisting Types: Shock resisting types of tool steels can easily resist shock at any given temperature. The tensile strength of this type of tool steel is acquired by making its carbon content low. This type of tool steel can only resist impact, not abrasions. Shock resisting tool steels can be used in battering tools, cold or hot gripper, cold or hot swaging, and chipper knives.

Tool steels are used in various applications because of their resistance to abrasion and impact, hardness, and the ability to withstand extreme temperatures and pressures. They can truly help in fabricating different sets of tools that are intended for numerous industries.
