ALLOY 904L • UNS N08904 • WNR 1.4539

UNS NO8904, inowanzozivikanwa se 904L, isimbi yakadzika kabhoni yakakwira alloy austenitic simbi isina tsvina iyo inoshandiswa zvakanyanya mumaapplication apo iyo corrosion properties yeAISI 316L uye AISI 317L haina kukwana.

Kuwedzerwa kwemhangura kune iyi giredhi kunoipa iyo isingadziviriri zvivakwa zvepamusoro kune yakajairwa chrome nickel simbi isina tsvina, kunyanya kune sulphuric, phosphoric uye acetic acids. Zvisinei, kune kushandiswa kuduku nehydrochloric acids. Iyo zvakare ine yakanyanya kupikisa kupinza mu chloride mhinduro, kupikisa kwakanyanya kune ese ari maviri crevice uye kusagadzikana corrosion kupaza. Alloy 904L inoita zvirinani kupfuura mamwe austenitic Stainless simbi nekuda kwekukwira kwepamusoro kwe nickel uye molybdenum.
