Model Number: Cr12-#7234
Brand Name: Jinshan
Key Specifications/Special Features:
Cr12 mold steel is one of the high-carbon steel chromium cold work die steel representativesContains a high amount C 2.00to2.30% and Cr 11.00to13.00%, belongs to ledeburite, so there is a high hardenability, hardened and abrasion resistance, small deformation hardening but when carbide heterogeneity, multi-directional deformation and irregular, poor organization is its main drawbackUneven carbide difficult to improve the heat treatment method, unless use powder metallurgy manufactureCr12 mold steel impact toughness poor thermal conductivity and high temperature ductility is poor, should pay attention to heating and thermal processing forging processTesting: in accordance with GB/T4162, 6402, 4370, SEP1921 or inspection standards 100% one by one testing according to user requirements, ensure inspection qualify
Delivery status: steel is annealed condition of delivery
Specification of heat treatment:
- Quench, 950 to 1000℃ oil cooling
- Quench 980°C, oil cooling, 180°Ctemperature 2 hours
