  冷拔精密无缝钢管主要标准及材质

  根据冷拔精密无缝钢管是一种通过精拔或冷轧处理后的一种高精密的钢管材料,由于冷拔精密无缝钢管内外壁无氧化层,承受高压无泄漏,高精度,高光洁度,冷弯不变形,扩口,压扁无裂缝等有点,所以主要用来生产气动或液压元件的产品,如气缸或油缸,可以是无缝管,也有焊接管,冷拔精密无缝钢管的化学成分有碳C,硅Si,锰Mn,硫S,磷P,铬Cr。

  ZHUYAOCAIZHI:10#,20#,35,45,40Cr,25Mn,37Mn5,St35(E235),St37.4,St45(E255),St52(E355)。

  冷拔精密无缝钢管主要用途:汽车,机械配件等对钢管的精度,光洁度有很高要求的机械,精密钢管用户不仅仅是对精度,光洁度要求比较高的用户了,因冷拔精密无缝钢管精度高,公差能保持在2--8丝,所以很多机械加工用户为了节省工,料,时的损耗,将无缝钢管或者圆钢正慢慢的转变为冷拔精密无缝钢管。
