Professional Supplier 1.2379 D2  Steel Tool Steel Sheet


Product Description

Chemical composition(mass fraction)(wt.%) of the 1.2379




1.2379 AISI D2 is a high carbon, high chromium, molybdenum, vanadium, air hardening tool steel which offershigh surface hardness, good wear resistance, through hardening properties, dimensional stability and high resistance to tempering effect. 1.2379 X155CrVMo12-1 tool steel is also suitable for vacuum hardening.

1.2379 AISI D2 is one of the cold work, high carbon, high chromium type tool steels. D2 is a deep hardening, highly wear resistant alloy. It hardens upon air cooling so as to have minimum distortion after heat treatment.

1.2379 AISI D2 tool steel used for long run tooling applications where wear resistance is important, such as blanking or forming dies and thread rolling dies, cutting tools, stamping, woodworking, moulding tools for plastics. Toughness better than in D3. Possibility of nitriding.

Heat Treatment and manufacture

DIN 1.2379 Tool Steel Heat treatment and manufactured as below:

  • Forged 

Slowly Heat to 1065ºC~954ºC for Forging the 1.2379 cold work tool steel. No forge below 926ºC.

  • Annealing

Heat to 871~898ºC, Then slowly cooling at 4.4ºC per hour or less in heat treatment furnace.

  • Quenching & Tempering

For get better Mechanical properties of 1.2379 steel, Q+T the steel material is necessary.  1.2379 Tool steels Quenching at 1020~1040ºC, cool in oil or air; Tempering at 180~250ºC.

After tempering hardness HRC | 100 ℃: 63
After tempering hardness HRC | 200 ℃: 61
After tempering hardness HRC | 300 ℃: 59
After tempering hardness HRC | 400 ℃: 58
