904L ndiro yesimbi isina tsvinaimhando ye austenitic Stainless simbi ine yakaderera kabhoni yemukati uye yakakwirira alloying yakagadzirirwa nharaunda dzine hutsinye hwekuora. Iine zviri nani corrosion resistance pane316Luye317L, uchifunga nezve mutengo, kuita, uye mutengo-kubudirira. kumusoro. Nekuda kwekuwedzera kwe1.5% mhangura, ine yakanakisa corrosion resistance painoderedza maasidhi akaita sesulfuric acid uye phosphoric acid. Iyo zvakare ine yakanakisa corrosion kuramba kurwisa kusagadzikana corrosion pitting uye crevice corrosion inokonzerwa ne chloride ion, uye ine kumira kwakanaka kune intergranular corrosion. Mune yakachena sulfuric acid muhuwandu hwehuwandu hwe0-98%, tembiricha yebasa ye904L simbi ndiro inogona kunge yakakwira kusvika 40 degrees Celsius. Mune yakachena phosphoric acid muhuwandu hwehuwandu hwe0-85%, kupikisa kwayo kwekuora kwakanaka kwazvo. Muindasitiri phosphoric acid inogadzirwa nekunyorova maitiro, tsvina ine simba rakasimba pakuramba kwecorrosion. Pakati pemarudzi ese ephosphoric acid, 904L super austenitic simbi isina ngura ine simbi iri nani inodzivirira pane yakajairwa simbi isina tsvina. Mune yakasimba oxidizing acids, 904L simbi isina tsvina ine yakaderera corrosion resistance pane akasiyana ane alloyed simbi mhando. mukati meiyi concentration range. Iyo 904L simbi inodzivirira ngura iri nani pane yeyakajairwa Stainless simbi. 904L simbi isina tsvina ine yakakwira kuramba kugomba ngura. Kupokana kwayo kune crevice corrosion mune chloride mhinduro. Simba racho rakanaka zvakare. Iyo yakakwira nickel yemukati ye904L simbi ndiroinoderedza chiyero chekuora mumakomba uye seams. Nekuda kweiyo yakakwira nickel yemukati, 904L ine yakanyanya kupikisa kushushikana nekuora kwekuputika mune nitride mhinduro, yakadzika hydroxide mhinduro uye hydrogen sulfide-rich nharaunda.
