不銹鋼無(wú)縫管固溶處理可提高性能的作用。不銹鋼無(wú)縫管為什么要固溶處理？不銹鋼無(wú)縫管的固溶溫度主要根據(jù)化學(xué)成分確定，其合金元素種類多、含量高的牌號(hào)，固溶溫度要相應(yīng)提高。特別是錳、鉬、鎳、硅含量高的不銹鋼，提高固溶溫度，使其充分溶解，才能達(dá)到軟化效果。但穩(wěn)定化鋼，固溶溫度高時(shí)穩(wěn)定化元素的碳化物充分溶解于奧氏體中，在隨后的冷卻中會(huì)以Cr23C6的形態(tài)在晶界析出，造成晶間腐蝕。為使穩(wěn)定化元素的碳化物(TiC和NbC)不分解、不固溶，一般采用下限固溶溫度。綜上所述，不銹鋼無(wú)縫管的固溶處理有三個(gè)要素是溫度、保溫時(shí)間和冷卻速度。
