Oct 12, 2018 · D-2 steel can be either oil-hardened or air-hardened, and contains a higher percentage of carbon and chromium than O-1 and A-2 steel. It has a high wear resistance, good toughness and low distortion after heat treating. The higher carbon and chromium levels in D-2 steel make it a good choice for applications requiring a longer tool life.

A-6 may be annealed in either a controlled atmosphere furnace or wrapped in stainless steel foil. Heat to 1350° to 0°F and hold approximately one hour for each inch of thickness. Cool very slowly at a rate of 20° per hour to approximately 1000°F. Annealed hardness range is normally 212 to 235 Brinell.
Chinese Steel Industry Suppliers - Tool Die SteelsHot-resistant steels and alloys are covered by the AIR 9165 standard. Tool and die steels are high carbon steels (either carbon or alloy) possessing high hardness, strength and wear resistance.

Effects of tempering temperature on impact wear of 30Cr3Mo2WNi hot-working die steel are investigated by SEM, TEM, hardness, and impact wear tests. From 300 to 680°C, the hardness of the steel decreases and the impact toughness increases with increasing tempering temperature, while a secondary hardening with maximum hardness, 48.6 HRC, is achieved at 550°C.

Tool Steel Resource Guide A2, D2, M2, S7, O1, W1, A6 M42 tool steel is a molybdenum high speed tool steel with 8-10% cobalt added for increased hardness and hot hardness that is superior to other high speed grades. This results in a sharper cutting edge that lasts longer, even when being used to machine high-hardness and hard-to-machine alloys in heavy duty and high production applications.
