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--錳奧氏體不鏽鋼,性能優於201不鏽鋼。

201不鏽鋼管:屬於鉻--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。
