904L roostevabast terasest varras_Tianjin Fang Steel Steel Co., Ltd.

904L Roostevabast terasest varras

904LKlass on ebastabiilne madala süsinikusisaldusega kõrge legeeritud austeniitne roostevaba teras。Lisage vask sellele tasemele, et suurendada selle vastupidavust tugevatele redutseerivatele hapetele，Eriti on oluliselt paranenud vastupidavus väävelhappele。Samuti on tal tugev vastupidavus kloriidi erosioonile，Sealhulgas kaevude korrosioon/Lõhe- ja pingekorosioonipragunemine。
