style="text-indent:25px">一般來說，合金圓鋼知識易離子化的金屬容易氧化，即容易腐蝕，而事實(shí)上并非完全如此，有些金屬如鋁、鎂、鉻等雖然易離子化，但由于它們在大氣或水中容易生成一層腐蝕產(chǎn)物的薄膜，從而卻提高了耐蝕性。通過化學(xué)或電化學(xué)方法使鋁及鋁合金屬表面狀態(tài)發(fā)生變化，使其溶解速度急劇下降，使耐蝕性提高，此種工藝過程稱為鋁材鈍化處理。鈍化往往伴隨陽極電位突然升高，從而使陽極反應(yīng)難以進(jìn)行，使金屬腐蝕速度減慢或停止。鈍化其實(shí)是通過鈍化液的化學(xué)反應(yīng)，把活潑的金屬表層變成惰性的表層，從而阻止外界有破壞性的物質(zhì)與金屬表面產(chǎn)生反應(yīng)，從而達(dá)到延長生銹時間的目的。福建5crnimo圓鋼合金圓鋼在氯離子存在下的環(huán)境中，腐蝕很快。</p><div

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。合金圓鋼硬度很高，不容易變形。福建5crnimo圓鋼</p><p
