1.2379 steel is Ledeburitic 12% chrome steel, very high resistanceagainst abrasive and adhesive wear due to a highvolume of hard carbides in the steel matrix, goodtoughness,very gooddimensional stability, highcompressive strength, very good base material forPVD/CVD coating as well as nitriding due to itssecondary hardening properties.
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:
DIN 1.2379 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
