ALOY 904L • UNS N08904 • WNR 1.4539

UNS NO8904, oo loo yaqaan 904L, waa kaarboon hoose oo austenitic ahama bir ah oo si weyn loogu isticmaalo codsiyada halka sifooyinka daxalka ee AISI 316L iyo AISI 317L aysan ku filneyn.

Ku darida naxaasta ee darajadan waxay siinaysaa sifooyin u adkaysta daxalka oo ka sarreeya birta caadiga ah ee chrome nikkel, gaar ahaan sulphuric, phosphoric iyo acetic acids. Si kastaba ha ahaatee, waxaa jira isticmaalka xaddidan ee acids hydrochloric. Waxa kale oo ay leedahay iska caabin heersare ah oo ay ku daadinayso xalalka chloride-ka, iska caabin sare oo u ah dildilaaca daxalka labadaba. Alloy 904L wuxuu u shaqeeyaa si ka wanaagsan biraha kale ee austenitic ahama sababtoo ah alloying sare ee nikkel iyo molybdenum.
