Product brief introduction

KD5 Hot-work die steel, is a common die casting die steel, high strength and hardness, good cold and hot fatigue resistance, and good hardenability, but its poor toughness and plasticity.
Used under high temperature, high stress, not affected by the impact load of punch and die, die casting, such as hot extrusion die, forging die, non-ferrous metal forming mould, etc.

Technical Equipment

Purpose: die casting die steel in common use.
Carbon content is low, have high toughness and good thermal conductivity;
At the same time, with higher chromium carbide forming elements, tungsten, vanadium, phase transition temperature increased, the steel has high temperature strength, high hardness and good thermal fatigue resistance;
Hardening.
Suitable for high temperature, high stress, but is not affected by impact load of the die casting copper, aluminum, magnesium alloy using the attached mold, core, runner set, split nails, la stress with high pressure, shear knife, hot forging die, forging machine intensive, blocks, etc.
