摘要
新研制的塑料模具钢为 4Cr2Mn2NiMoV ,经金相分析和力学性能检验及厂家使用表明 ,其特点是淬透性及抛光性能良好 ,预硬处理后经机械加工即可直接使用 ,是一种值得推广的新钢种。
After determination of metallographical,mechanical testing for metals and used by factories,it shows that the new developed 4Cr2Mn2NiMoV steel for plastic moulds has excellent permeability and glazing.After hardening pretreatment and machining,the new steel can be used directly.This new steel is worthy of spread.
