DIN EN 1.2379 Steel X153CrMoV12 Material Equivalent, Datasheet, Properties


DIN EN 1.2379 Steel (X153CrMoV12 Material)現(xiàn)貨價格查詢

 

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.
