I-ALLOY 904L • UNS N08904 • WNR 1.4539

I-UNS NO8904, eyaziwa ngokuba yi-904L, yintsimbi ephantsi ye-carbon high alloy austenitic stainless steel stainless steel stainless steel stainless steel stainless steel stainless steel esetyenziswa kakhulu kwizicelo apho iipropathi zokubola ze-AISI 316L kunye ne-AISI 317L ayanelanga.

Ukongezwa kobhedu kweli nqanaba linika iipropathi ezixhathisayo ku-corrosion ngaphezu kwe-chrome nickel ye-stainless steels eqhelekileyo, ngakumbi kwi-sulphuric, i-phosphoric kunye ne-acetic acids. Nangona kunjalo, kukho ukusetyenziswa okulinganiselweyo kunye ne-hydrochloric acids. Ikwanayo nokumelana okuphezulu kokungena kwizisombululo zekloridi, ukuxhathisa okuphezulu kuzo zombini iintanda kunye noxinzelelo lwe-corrosion cracking. I-alloy 904L yenza ngcono kunezinye i-austenitic stainless steels ngenxa ye-alloying ephezulu ye-nickel kunye ne-molybdenum.
