Hot Rolled DIN 1.2379 Tool Steel Round Bar

Hot Rolled DIN 1.2379 Tool Steel 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.
