9SiCr鋼是低合金刃具用鋼，但也常常制作冷作模具零件，效果很好。它比鉻鋼（Cr2或9Cr2）有更高的淬透性和淬硬性并且有較高的回火穩(wěn)定性。適合分級淬火或等溫淬火。該鋼**早引自前蘇聯(lián)的9XC，過去曾稱作9CrSi鋼。成分和性能與9XC完全一樣。在我國已有很長的應(yīng)用歷史。外國同類鋼號*有德國的90CrSi5瑞典的2092和SR1855，DF-1。其他國家未見有相似鋼號。該鋼可作多種形狀復(fù)雜，變形要求小的冷作模。該鋼鍛造性能良好，由于易脫碳，需要在中性氣氛或者保護(hù)氣氛爐中加熱。施以鍛熱調(diào)質(zhì)處理，可以獲得細(xì)密的回火索氏體組織，簡化工藝，省時節(jié)電，既有良好的切削加工性能，又有理想的余熱處理組織。模具鋼該鋼受熱軟化溫度為320℃，淬透性比鉻鋼好，油淬淬硬性深度40—50mm。該鋼零保溫淬火韌化工藝，可以消除搓絲=板因常規(guī)淬火加熱氧化脫碳造成的早期失效，不均勻奧氏體修或可以細(xì)化馬氏體，搓火后得到隱晶馬氏體或者細(xì)針狀馬氏體，這種組織強(qiáng)韌性好。9SiCr量具刃具用鋼，是常用的低合金工具鋼，具有較高的淬透性和淬硬性，以及較高的回火穩(wěn)定性。威海2CR13圓鋼總代理</p><p
