</p> <p> 影響不銹鋼銹蝕的主要因素有三點(diǎn)： </p> <p> <br /> </p> <p> 1）合金元素的的含量，一般地說(shuō)鉻的含量在10.5%鋼就不易生銹了。鉻鎳的 </p> <p> <br /> </p> <p> 含量越高防腐性就越好，如304材質(zhì)鎳要的含量在8-10%，鉻的含量達(dá)到18-20%，這樣的不銹鋼在一般情況下是不會(huì)生銹的。 </p> <p> <br /> </p> <p> 2）生產(chǎn)企業(yè)的冶煉工藝也會(huì)影響不銹鋼的耐腐蝕性。冶煉技術(shù)好、設(shè)備先進(jìn)、工藝先進(jìn)的大的不銹鋼廠無(wú)論是在合金元素的控制，雜質(zhì)的去除、鋼坯冷卻溫度的控制都能得到保證，因此產(chǎn)品質(zhì)量穩(wěn)定可靠，內(nèi)在質(zhì)量好,不易生銹。反之一些小的鋼廠設(shè)備落后，工藝落后，冶煉過(guò)程中，雜質(zhì)不能去除，生產(chǎn)的產(chǎn)品難免會(huì)生銹。 </p> <p> <br /> </p> <p> 3）外部環(huán)境，氣候干燥通風(fēng)好的環(huán)境不易生銹。而空氣濕度大，連續(xù)陰雨天氣、或空氣中含酸堿度大的環(huán)境地區(qū)就易生銹。304材質(zhì)不銹鋼，如果周邊環(huán)境太差也是會(huì)生銹的。 </p> <p> <br /> </p> <p> <br />
