It also is called din 1 2379 and jis skd11 steel.
Polished d2 steel sheet.
The high percentage of chromium gives it mild corrosion resisting properties in the harden condition.
These carbides provide good resistance to wear from sliding contact with other metals and abrasive materials.
It is a high carbon and high chromium cold work mold steel.
The d2 tool steel grade has high proportions of carbon and chromium for greater resistance to wear than a2 and a6 tool steel.
The d2 tool steel sheet has been precision ground meets american society for testing and materials international astm a681 specifications and has a standard tolerance.
It is widely used in the world.
D2 tool steel is a versatile high carbon high chromium air hardening tool steel that is characterized by a relatively high attainable hardness and numerous large chromium rich alloy carbides in the microstructure.
D2 steel round bar and plate can be used to produce cold work mold with a large cross section complex shape high impact force and high wear resistance.
It is a very deep hardening steel and will be practically free from size change after proper treatment.
D2 flat ground is ground to a surface finish of up to 35ra on six sides and is free from defects and decarburization.
