產(chǎn)品編號(hào) Q550NH耐候鋼

产品说明
产品参数

耐候鋼的合金成分及重量百分比含量為：C：0.12～0.21、Si：0.2～2.0、Mn：0.7～2.0、S≤0.036、P≤0.034、Cu：0.10～0.40、Al<0.2，其余為Fe和微量雜質(zhì)。通過Cu、 Mn、Si、Al等合金化，并簡(jiǎn)單調(diào)整普通低碳鋼(Q235鋼)的部分元素含量，在不需改變Q235鋼生產(chǎn)工藝條件下，就能生產(chǎn)出具有良好的耐大氣腐蝕性能、綜合機(jī)械性能的經(jīng)濟(jì)耐候鋼。

耐候鋼（即耐大氣腐蝕鋼）在融入現(xiàn)代冶金新機(jī)制、新技術(shù)和新工藝后得以可持續(xù)發(fā)展和創(chuàng)新，屬超級(jí)鋼技術(shù)前沿水平的系列鋼種之一。耐候鋼由普碳鋼添加少量銅、鎳等耐腐蝕元素而成，具有優(yōu)質(zhì)鋼的強(qiáng)韌、塑延、成型、焊割、磨蝕、高溫、疲勞等特性；耐候性為普碳鋼的2~8倍，涂裝性為普碳鋼的1.5~10倍，能減薄使用、裸露使用或簡(jiǎn)化涂裝使用。該鋼種具有耐銹，使構(gòu)件抗腐蝕延壽、減薄降耗，省工節(jié)能的特性，使構(gòu)件制造者、使用者受益。而目前制造該鋼種的精英人才，也是目前我國(guó)的，目前收納耐候鋼人才較多的有鋼鐵英才網(wǎng)。耐候鋼產(chǎn)品供制造集裝箱、鐵道車輛、石油井架、海港建筑、采油平臺(tái)及化工石油設(shè)備中含硫化氫腐蝕介質(zhì)的容器等結(jié)構(gòu)件。
