Khoom Taw qhia

904L stainless hlau yeeb nkab, tseem hu ua super stainless hlau, muaj corrosion kuj zoo nyob rau hauv dilute sulfuric acid. Nyob rau hauv ntshiab sulfuric acid nrog ib tug concentration ntawm 0-98%, qhov kev pab cuam kub ntawm 1.4539 stainless hlau round yeeb nkab yuav ua tau siab li 40 degrees Celsius. Nyob rau hauv ntshiab phosphoric acid nrog ib tug concentration ntawm 0-85%, nws corrosion kuj zoo heev.Stainless hlau 904L yeeb nkabsuav nrog stainless hlau seamless kav thiab welded kav, uas yog tshwj xeeb tshaj yog haum rau lub sij hawm uas muaj zog corrosive, kub kub, siab siab thiab lwm yam yuav tsum tau.
