DIN 1.2379 Tool Steel Forged Round Bar

DIN 1.2379 Tool Steel Forged Round Bar

1: DIN 1.2379 Steel Introduction

DIN 1.2379 steel is a high carbon chromium-molybdenum-vanadium cold work tool steel with excellent wear resistance, good dimensional stability, toughness and hardening properties. Due to its secondary hardening characteristics, it is easily treated with supplemental nitriding and surface coatings. The high chromium content improves its wear resistance and toughness, helping to resist corrosion; vanadium gives the steel a finer grain structure, preventing overgrowth of grains and improving hardenability; and molybdenum increases its high temperature resistance and hardenability, improving its corrosion and wear resistance.

Annealing

At 800~850°C, followed by cooling to 600°C at a cooling rate of 10°C/h, and then air-cooled to a hardness of ≤250HBw.

Hardening

At 975~1040°C, followed by oil or gas cooling.

Tempering

Including low temperature tempering and high temperature tempering. Low temperature tempering temperature is 150~200°C, hardness ≥61HRC; high temperature tempering temperature is 480~540°C, hardness ≥58HRC.
