不同材质的不锈钢管性能特点及用途
304不锈钢焊管：具有良好的耐蚀性、耐热性、低温强度和机械特性，冲压、弯曲等热加工性好，无热处理硬化现象。用途：餐具，橱柜，锅炉，汽车配件，医疗器具，建材，食品工业。
310不锈钢管主要特点是：耐高温，一般使用锅炉内、汽车排气管，其他性能一般。
303不锈钢管：通过添加少量的硫、磷使其较304更易切削加工，其他性能与与304不锈钢无缝管相似。
302不锈钢管：302不锈钢棒广泛用于汽车配件、航空、航天五金工具，化工。具体如下：工艺品，轴承，滑花，医疗仪器，电器等。特性：302不锈钢球属于奥氏体型钢，与304比较接近，但是302的硬度更高一些，HRC≤28，具有良好的防锈及防腐性。
301不锈钢焊管：延展性好，用于成型产品。也可通过机械加工使其迅速硬化，焊接性好。抗磨性和疲劳强度优于304不锈钢管。
202不锈钢管：属于铬-镍-锰奥氏体不锈钢，性能优于201不锈钢。
201不锈钢管：属于铬-镍-锰奥氏体不锈钢，磁性比较低。
410不锈钢管：属于马氏体(高强度铬钢)，耐磨性好，抗腐蚀性较差。
420不锈钢管：“刃具级”马氏体钢，类似布氏高铬钢这种*早的不锈钢。也用于外科手术刀具，可以做的非常光亮。
304L不锈钢管：作为低碳的304钢，在一般情况下，耐腐蚀性与304相似，但在焊接后或者消除应力后，其抗晶界腐蚀能力优良，在未进行热处理情况下，也能保持良好的耐腐蚀性。
310不锈钢焊管：主要特点是耐高温，一般使用锅炉内，汽车排气管。其他性能一般。
1、铁素体不锈钢。含铬12%～30%。其耐蚀性、韧性和可焊性随含铬量的增加而提高，耐氯化物应力腐蚀性能优于其他种类不锈钢。
2、奥氏体不锈钢。含铬大于18%，还含有8%左右的镍及少量钼、钛、氮等元素。综合性能好可耐多种介质腐蚀。
3、奥氏体-铁素体双相不锈钢。兼有奥氏体和铁素体不锈钢的优点，并具有超塑性。
4、马氏体不锈钢。强度高，但塑性和可焊性较差。
