1.2311 MOLD STEEL
Standard: equivalent to China 3Cr2Mo, Sweden (ASSAB) 618, United States P20, Japan (Hitachi) HPM2
1.2311 mold steel has good comprehensive mechanical properties, high hardenability, and good polishing performance. It can achieve relatively uniform hardness for large-section steel (with a maximum pre hardening thickness of 700mm), which not only ensures the performance of the mold, but also reduces the production cycle and cost of the mold.
Main application: mainly used for molds with high surface finish requirements (such as home appliance shells and automotive interiors)
Ornaments, etc.), this steel grade is suitable for making large and medium-sized plastic molds.
