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 .

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.
