Grade Introduction:
DIN 1.2379 Steel (X153CrMoV12 Material) is a high carbon chromium molybdenum vanadium cold worked tool steel with high wear resistance, good dimensional stability, toughness and hardenability. Due to the secondary hardening properties, it is easy to carry out supplementary nitriding and surface coating. High chromium increases wear resistance and toughness and contributes to corrosion resistance; Vanadium gives steel a finer grain structure and prevents excessive grain growth and improves hardenability of steel; Molybdenum increases heat resistance and hardenability, improve corrosion and wear resistance.
DIN 2379 steel is Cold Work Steel with High Carbon High Chromium contents. The Quality with high wear resistant and toughness properties due to Vanadium addition of 0.90% . Normally it supply condition is an Annealed and will offer hardness to reach 57-59 HRC. It can be machinable in the annealed condition. DIN 2379 is the superior steels than D3 due to high alloys properties.
Grade Application:
DIN 2379 tool steel applicable for cold stamping or forming dies, cold forming rolls, Chipper knives, Punches, slitters, shear blades, tools, tyre shredders, trimming, cutting Threading Dies , stamping tools Etc.
