904L simbi isina ngura ndiroimhando yesimbi isingasvibiswi inonyungudika ine kabhoni shoma uye ine alloying yakawanda yakagadzirirwa nzvimbo dzine ngura dzakaoma. Inodzivirira ngura zviri nani pane316Luye317L, tichifunga nezvemutengo, mashandiro, uye kushanda zvakanaka kwemari. Yakakwira. Nekuda kwekuwedzera 1.5% copper, ine ngura yakasimba inodzivirira kuderedza maacid akadai sesulfuric acid nephosphoric acid. Inewo ngura yakanaka inodzivirira stress corrosion pitting uye crevice corrosion inokonzerwa ne chloride ions, uye ine ngura yakanaka inodzivirira corrosion pakati pe granular. Mu sulfuric acid yakachena iri pakati pe 0-98%, tembiricha yekushanda ye 904L steel plate inogona kusvika 40 degrees Celsius. Mu phosphoric acid yakachena iri pakati pe 0-85%, ngura yayo yakanaka kwazvo. Mu industrial phosphoric acid inogadzirwa ne wet processes, tsvina ine simba guru pakurwisa corrosion. Pakati pemarudzi ese e phosphoric acid, 904L super austenitic stainless steel ine ngura iri nani pane simbi isingatsvedzeri. Mu strong oxidizing acids, 904L stainless steel ine ngura yakaderera pane mhando dzakasiyana dzesimbi dzakanyatsogadzirwa. mukati meiyi concentration range. 904L stainless steel iri nani pane ye common stainless steel. Simbi isingatsvi 904L inodzivirira ngura zvakanyanya. Inodzivirira ngura yakatsemuka mumhinduro dzechloride. Simba rayo rakanakawo. Nickel yakawanda904L ndiro yesimbiinoderedza mwero wekuora mumakomba nemaseams. Nekuda kwehuwandu hwayo hwakawanda hwe nickel, 904L inodzivirira kupwanyika kwe stress corrosion mu nitride solutions, concentrated hydroxide solutions uye hydrogen sulfide-rich environments.
