310s不銹鋼管的高溫滲氮工藝

 

310s不銹鋼管在加熱溫度不低于1200℃、保溫時間不小于24h、氮氣壓力不低于0.2MPa的工藝條件下,可以在不銹鋼中獲得單側厚度約在2.0mm以上的滲氮層。310s不銹鋼管對于厚度在5.0眥n以下的試樣,則可以做到完全貫穿滲氮,其中經1200℃/0.3MPa/h工藝路線處理的厚度為4.2mm的試樣已經全奧氏體化,310s不銹鋼管用億436氧氮測定儀測得平均氮含量為1.0%。

因此,采用高溫滲氮工藝來提高不銹鋼表面的氮含量是行之有效的。通過高溫高壓短時間表面滲氮,可使不銹鋼表面獲得高性能的高氮層,310s不銹鋼管并使鐵素體不銹鋼或雙相不銹鋼通過滲氮發生奧氏體轉變,獲
