D2 COLD WORK TOOL STEEL

Chemiscal composition：

Heat Treatment:

Forge: at 900℃-1100℃ Cool slowly and anneal immediately

Annealing: at 830℃-860℃ Cool slowly in furnace

Stress Relieving: at to 650℃-700℃ Cool in furnace or still air

Hardening: Preheat at 650℃-850℃ raise to 1000℃-1050℃ Cool in air, oil or into hot bath held at 500℃-550℃ and then air cool

AISI d2 tool steel hardness Annealed 255.

The specialty of the steel:

AISI D2 tool steel is 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.

Main uses:

Cutting, punching, stamping tools, shear blades, thread rolling dies, cold extrusion dies, drawing and bending tools, flanging and straightening rolls, fine cutting tools deep drawing tools, plastic moulds for abrasive polymers
