5Cr2NiMoVSi 5Cr2NiMoVSi are large cross-section steel hot forging die steel with high hardenability. Steel tendency to austenite grain growth when heated small, wide range of heating temperature heat treatment, steel, thermal stability, thermal fatigue properties and impact toughness, suitable for manufacturing large cross-section of the press and hammer forging heat for mold.
