Product Description
1.2379 is a tool steel with a carbon content of 1.5%, a chromium content of 11.5%, and a hardness of up to 60HRC after heat treatment. It is a kind of semi-stainless steel. D2 steel has good wear resistance and moderate toughness. The disadvantage is that the corrosion resistance is slightly insufficient. It is a kind of steel that is more suitable for practical use. Bob Dozier likes to use D-2. D2 steel is highly wear-resistant, slightly deformed cold work die steel, wind-hardened tool steel. D2 steel can be used to manufacture cold work die steels with large cross-sections, complex shapes, high impact resistance, and high wear resistance, such as silicon steel sheet die, cold cutting scissors, trimming die, etc.
Basic Information
1.2379 The high carbon and high chromium cold work die steel widely used in the world is a ledeburite steel with high
hardenability, hardenability and high wear resistance; good high temperature oxidation resistance, rust resistance after quenching
and polishing Good capacity, small heat treatment deformation.
hardness
Annealing ≤255HB, indentation diameter ≥3.8mm;
Quenching ≥59HRC
Heat treatment specification
Quenching, 820±15℃ preheating, 1000±6℃ (salt bath) or 1010±6℃ (furnace control atmosphere) heating,
Keep heat for 10-20min, air cooling, tempering at 200±6℃.
Material characteristics
1.2379 steel is a high wear-resistant micro-deformation cold work die steel, which belongs to wind-hardened tool steel. The mass
fraction of carbon in this steel is as high as 1.5%, and the mass fraction of chromium is as high as 11.5%. After heat treatment,
the hardness can reach 60HRC, but the ductility, toughness and rust resistance are relatively weak, and the surface of the steel
is difficult to be mirror polished. With the development of cold stamping products toward high precision, high efficiency, and
multiple varieties, mold steels are required to have better wear resistance and toughness. Compared with Cr12MoV steel, the
chemical composition of this steel is increased with Mo and V, which changes the casting structure of the steel and improves the
morphology of cabochonite. The strength and toughness and wear resistance are better than those of Cr12MoV steel, which improves
the use of molds. life. Since the yield point and plastic deformation resistance of this steel are higher than those of Cr12MoV
steel, its forging performance and thermoplastic formability are slightly worse than those of Cr12MoV steel.

Scope of use
Suitable for tool steels with complex and possible deformations, various cold stamping dies with high wear resistance and long
life, cold shearing blades, thread rolling plates; cold extrusion forming, drawing dies, stainless steel sheets and high hardness
materials. Mode etc.
typical application
1) It is used for the deep drawing die of the rear cover of the refrigerator compressor, the quenching hardness is 56~58HRC.
2) In order to improve the service life of D2 cold work die flat steel rolling material, the method of adding rare earth is
adopted, the wear resistance and impact toughness of the steel are greatly improved, so as to achieve the purpose of improving the
service life of the round die flat steel rolling material .
3) Because the content of V and Mo in 1.2379 steel is higher than that of Cr12MoV steel, it has better overall performance, while
traditional Cr12MoV steel will gradually be replaced.
4) The rolling wheel and off-stage adjusting plate cold punching die made of D2 steel can increase the service life by 5 to 6
times compared with Cr12MoV steel.
