904 ndiro yesimbi isina tsvinaimhando ye austenitic Stainless simbi ine yakaderera kabhoni yemukati uye yakakwirira alloying yakagadzirirwa nharaunda dzine hutsinye hwekuora.Iyo ine zvirinani corrosion resistance pane 316L uye 317L, uchifunga nezve zvese mutengo uye kuita.Kukosha kwakanaka kwemari.Nekuda kwekuwedzera kwe1.5% mhangura, ine yakanakisa corrosion resistance painodzikisira maasidhi akaita sesulfuric acid uye phosphoric acid.Iyo zvakare ine yakanakisa corrosion yekudzivirira kurwisa kusagadzikana corrosion, gomba uye crevice corrosion inokonzerwa neakaomesesa ion, uye ine kumira kwakanaka kune intergranular corrosion.Mune yakachena sulfuric acid muhuwandu hwehuwandu hwe0-98%, tembiricha yebasa ye904L simbi ndiro inogona kukwira se40 degrees Fahrenheit.
Mune acid yakachena muhuwandu hwehuwandu hwe 0-85%, kupikisa kwayo kwekuora kwakanaka kwazvo.Muindasitiri phosphoric acid inogadzirwa nekunyorova maitiro, tsvina ine simba rakasimba pakuramba kwecorrosion.Pakati pemarudzi ese emaasidhi, 904L super austenitic simbi isina ngura ine simbi iri nani inodzivirira pane yakajairwa Stainless simbi.Muine oxidizing nitric acid yakasimba, 904L simbi isina tsvina ine kushomeka kwekushomeka pane simbi dzakasanganiswa kwazvo dzisina sirivha.Mu hydrochloric acid, kushandiswa kwe904L mahwendefa esimbi asina tsvinainongogumira kune yakaderera kudzika kwe1-2%.
