D2 1.2379 CR12MO1V1 Cold Work Mould Die Cast Alloy Steel Round Bar
D2 1.2379 CR12MO1V1 Cold Work Mould Die Cast Alloy Steel Round Bar
D2 Steel is extremely tough and durable! The high chromium content provides good corrosion resistance, ( but it can and will rust if it is not properly taken care of ). The blades are heat treated to a 62 Rockwell hardness and are guaranteed to retain their
factory edge for extended periods of heavy use. When it does come time to re-sharpen, the blades will hone to a razor edge.
Chemical composition(%):
| C | Cr | Mn | Mo | Si | V | P | S |
| 1.4-1.6 | 11-13 | 0.3-0.5 | 0.7-1.2 | 0.30-0.5 | ≤0.8 | ≤0.025 | ≤0.025 |
Application:
For metal stamping die, drawing die, stainless steel sheet punching die, high hardness punching die, cutting knife mold, Roll Die, metal parts production, machinery manufacturing etc.
Features:
1. Good processing, heat treatment size stability.
2. Excellent machinability.
3. Excellent dimensional stability when hardened.
4. After hardening and tempering, the high surface hardness match well with the toughness of the body.
Fabrication and Heat Treatment
Heat Treatment
D2 steels should be preheated very slowly to 815ºC (1500ºF) and then temperature can be increased to 1010ºC (1850ºF). They are then held at 1010ºC (1850ºF) for 20 to 45 minutes and air cooled (air quenched).
Forging
Forging of D2 steels can be done from 1065ºC (1950ºF) down to 954ºC (1750ºF). Do not forge below 926ºC (1700ºF).
Annealing
Annealing of D2 steels should be done at 871 to 898ºC (1600 to 1650ºF) followed by slow furnace cooling at 4.4ºC (40ºF) per hour or less.
Tempering
D2 steels can be tempered at 204ºC (400ºF) for achieving Rockwell C hardness of 61 and at 537ºC (1000ºF) for a Rockwell C hardness of 54.
Applications
D2 tool steels are used for long run tooling applications, where wear resistance is important, such as blanking or forming dies and thread rolling dies.
