不同材質(zhì)的不銹鋼管性能特點(diǎn)及用途
304不銹鋼焊管：具有良好的耐蝕性、耐熱性、低溫強(qiáng)度和機(jī)械特性，沖壓、彎曲等熱加工性好，無(wú)熱處理硬化現(xiàn)象。用途：餐具，櫥柜，鍋爐，汽車(chē)配件，醫(yī)療器具，建材，食品工業(yè)。
310不銹鋼管主要特點(diǎn)是：耐高溫，一般使用鍋爐內(nèi)、汽車(chē)排氣管，其他性能一般。
303不銹鋼管：通過(guò)添加少量的硫、磷使其較304更易切削加工，其他性能與與304不銹鋼無(wú)縫管相似。
302不銹鋼管：302不銹鋼棒廣泛用于汽車(chē)配件、航空、航天五金工具，化工。具體如下：工藝品，軸承，滑花，醫(yī)療儀器，電器等。特性：302不銹鋼球?qū)儆趭W氏體型鋼，與304比較接近，但是302的硬度更高一些，HRC≤28，具有良好的防銹及防腐性。
301不銹鋼焊管：延展性好，用于成型產(chǎn)品。也可通過(guò)機(jī)械加工使其迅速硬化，焊接性好。抗磨性和疲勞強(qiáng)度優(yōu)于304不銹鋼管。
202不銹鋼管：屬于鉻-鎳-錳奧氏體不銹鋼，性能優(yōu)于201不銹鋼。
201不銹鋼管：屬于鉻-鎳-錳奧氏體不銹鋼，磁性比較低。
410不銹鋼管：屬于馬氏體(高強(qiáng)度鉻鋼)，耐磨性好，抗腐蝕性較差。
420不銹鋼管：“刃具級(jí)”馬氏體鋼，類(lèi)似布氏高鉻鋼這種*早的不銹鋼。也用于外科手術(shù)刀具，可以做的非常光亮。
304L不銹鋼管：作為低碳的304鋼，在一般情況下，耐腐蝕性與304相似，但在焊接后或者消除應(yīng)力后，其抗晶界腐蝕能力優(yōu)良，在未進(jìn)行熱處理情況下，也能保持良好的耐腐蝕性。
310不銹鋼焊管：主要特點(diǎn)是耐高溫，一般使用鍋爐內(nèi)，汽車(chē)排氣管。其他性能一般。
1、鐵素體不銹鋼。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(yīng)力腐蝕性能優(yōu)于其他種類(lèi)不銹鋼。
2、奧氏體不銹鋼。含鉻大于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(zhì)腐蝕。
3、奧氏體-鐵素體雙相不銹鋼。兼有奧氏體和鐵素體不銹鋼的優(yōu)點(diǎn)，并具有超塑性。
4、馬氏體不銹鋼。強(qiáng)度高，但塑性和可焊性較差。
