不同材質的不鏽鋼管性能特點及用途
304不鏽鋼焊管：具有良好的耐蝕性、耐熱性、低溫強度和機械特性，衝壓、彎曲等熱加工性好，無熱處理硬化現象。用途：餐具，櫥櫃，鍋爐，汽車配件，醫療器具，建材，食品工業。
310不鏽鋼管主要特點是：耐高溫，一般使用鍋爐內、汽車排氣管，其他性能一般。
303不鏽鋼管：通過添加少量的硫、磷使其較304更易切削加工，其他性能與與304不鏽鋼無縫管相似。
302不鏽鋼管：302不鏽鋼棒廣泛用於汽車配件、航空、航天五金工具，化工。具體如下：工藝品，軸承，滑花，醫療儀器，電器等。特性：302不鏽鋼球屬於奧氏體型鋼，與304比較接近，但是302的硬度更高一些，HRC≤28，具有良好的防鏽及防腐性。
301不鏽鋼焊管：延展性好，用於成型產品。也可通過機械加工使其迅速硬化，焊接性好。抗磨性和疲勞強度優於304不鏽鋼管。
202不鏽鋼管：屬於鉻-鎳-錳奧氏體不鏽鋼，性能優於201不鏽鋼。
201不鏽鋼管：屬於鉻-鎳-錳奧氏體不鏽鋼，磁性比較低。
410不鏽鋼管：屬於馬氏體(高強度鉻鋼)，耐磨性好，抗腐蝕性較差。
420不鏽鋼管：“刃具級”馬氏體鋼，類似布氏高鉻鋼這種*早的不鏽鋼。也用於外科手術刀具，可以做的非常光亮。
304L不鏽鋼管：作為低碳的304鋼，在一般情況下，耐腐蝕性與304相似，但在焊接後或者消除應力後，其抗晶界腐蝕能力優良，在未進行熱處理情況下，也能保持良好的耐腐蝕性。
310不鏽鋼焊管：主要特點是耐高溫，一般使用鍋爐內，汽車排氣管。其他性能一般。
1、鐵素體不鏽鋼。含鉻12%～30%。其耐蝕性、韌性和可焊性隨含鉻量的增加而提高，耐氯化物應力腐蝕性能優於其他種類不鏽鋼。
2、奧氏體不鏽鋼。含鉻大於18%，還含有8%左右的鎳及少量鉬、鈦、氮等元素。綜合性能好可耐多種介質腐蝕。
3、奧氏體-鐵素體雙相不鏽鋼。兼有奧氏體和鐵素體不鏽鋼的優點，並具有超塑性。
4、馬氏體不鏽鋼。強度高，但塑性和可焊性較差。
