Tsananguro pfupi:

Machubhu eSimbi Isina Kuoma e904L. UNS N08904, inozivikanwa se904L, isimbi isina kuomarara ine alloy yakawanda uye inoshandiswa zvakanyanya mukushandiswa uko hunhu hweAISI 316L neAISI 317L husina kukwana. Iyi austenitic ine alloy yakawanda inodzivirira zvikuru kubva ku diluted sulfuric acid, phosphoric acid uye acetic acid. Inodzivirira kupwanyika kwe neutral chloride solutions. Kudzivirira kwayo kupwanyika kwe stress corrosion mune mamwe ma hot chloride kuri nani pane kwe lower nickel austenites. Iyi simbi ine kuumbwa kwakanaka uye weldability. Iyi simbi inowanikwa mumatanho ese akafanana seASTM neEN, zvisinei nemimwe misiyano. Dhizaini yekumanikidzwa kusvika ku370°C inosanganisirwa muASME II.
