DIN 1.2358 /60CrMoV18-5 Cold Worked Tool Steel
Superior Abrasion Resistance
DIN 1.2358’s high chromium content (10.50-12.00%) forms chromium carbides, delivering 30% higher wear resistance than conventional steels like O1. This makes it ideal for shear blades and blanking dies subjected to heavy abrasive loads.
Precision Heat Treatment
The steel’s oil or air quenching process achieves uniform hardness with minimal distortion (<0.05%). Double tempering further stabilizes dimensions, critical for precision tools like thread-rolling dies.
Broad Industrial Adaptability
From automotive stamping tools to plastic injection molds, DIN 1.2358 adapts to diverse applications. Its thermal stability (up to 500°C) and polishability enhance performance in both cold work and moderate high-temperature environments.

DIN 1.2358 / 60CrMoV18-5 Cold Worked Tool Steel
1.DIN 1.2358 Tool Steel Overview
DIN 1.2358 is a high-carbon, high-chromium cold work tool steel renowned for its exceptional hardness (60-64 HRC), wear resistance, and thermal stability. With a composition of 1.28-1.62% carbon and 10.50-12.00% chromium, it forms dense carbides that enhance durability in abrasive environments. Its optimized heat treatment process minimizes distortion, ensuring precision for complex tools like blanking dies and injection mold inserts. Widely used in automotive, aerospace, and manufacturing industries, DIN 1.2358 combines performance with cost-effectiveness, offering extended tool lifespan under extreme conditions.
