D2 1.2379 Cr12Mo1V1 alloy tool steel bar For Cold work mold
Introduction
D2 Tool steel apply to metal stamping die, drawing die, stainless
steel sheet stamping die, die with high hardness; Lightweight
materials used for cutting, thread rolling dies, drawing, pressure
pads ; highly wear-resistant plastic mold.Cold work D2 tool steel
containing high carbon high chromium. It with strong wear
resistance and hardening. Suit the production of a larger
interface, complex shape, heavy working conditions a variety of Die
and Tool .
Chemical Composition (%)
C | Si | Mn | P | S | Cr | Mo | V |
1.4-1.6 | 0.30-0.5 | 0.3-0.5 | ≤0.030 | ≤0.030 | 11-13 | 0.7-1.2 | ≤0.80 |
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.
