What is the hardness of D2 material?
D2 can reach an approximate tempered hardness range between 54 – 61 HRC and features an approximate compressive yield strength of around 275 ksi to around 319 ksi as hardness increases.
What material are punches made from?
Process. Punch tooling (punch and die) is often made of hardened steel or tungsten carbide. A die is located on the opposite side of the workpiece and supports the material around the perimeter of the hole and helps to localize the shearing forces for a cleaner edge.

What is the hardness of tool steel?
Hardness in tool steels is most commonly measured using the Rockwell C test. Hardened cold work tool steels are generally about 58/64 HRC (hardness Rockwell C), depending on the grade. Most are typically about 60/62 HRC, although some are occasionally used up to about 66 HRC.
What is OHNS?
Acronym. Definition. OHNS. Otolaryngology Head and Neck Surgery.
What grade is D2 steel?
D2 steel is air hardened and contains between 10% and 13% chromium (which is unusually high). D2 steel has a hardness in the range of 55 to 62 HRC, which makes is a very durable and high- end knife steel. D2 steel will retain its hardness up to a temperature of 425 °C (797 °F).
What is the hardness of hchcr-d2 steel?
HCHCR-D2 steel is Cold Work Steel with High Carbon High Chromium contents. The Quality with high wear resistant and toughness properties due to Vanadium addition of 0.90% . Normally it supply condition is an Annealed and will offer hardness to reach 57-59 HRC. It can be machinable in the annealed condition.
Who are the manufacturers of hchcr tool steel?
HCHCR Round Bars, HCHCR Round bar manufacturer, HCHCR Rods Supplier, HCHCR Stockist, HCHCR Dealers, HCHCR Distributors, HCHCR Wholesalers, HCHCR Steel Traders, HCHCR Steel Square Distributors, HCHCR Steel Flat Bar, HCHCR Steel Companies Near me. Cold-work tool steels which include D2, D3, D4, D5, and D7 steels are high-carbon, high-chromium steels.
Why is hchcr steel used at room temperature?
Hchcr Steel are normally used at room temperatures featuring good wear resistance, toughness and dimensional stability. Since they operate at room temperatures high temperature resistance is not required. To achieve wear resistance Higher hardness is recommended. For better impact strength steels with better toughness are suggested.
Which is the correct value for steel hardness?
Values are approximate and for guidance only. Reference Table: Steel hardness conversion chart – all values approximate. Since the various types of hardness tests do not all measure the same combination of material properties, conversion from one hardness scale to another is only an approximate process.
