Ibisobanuro bigufi:

Imiyoboro ya 904L Stainless Steel. UNS N08904, izwi cyane nka 904L, ni icyuma cya austenitic gifite alloy nyinshi kandi gifite karubone nkeya gikoreshwa cyane mu bikorwa aho imiterere ya AISI 316L na AISI 317L idahagije. Iki cyuma cya austenitic gifite alloy nyinshi kirwanya cyane ibitero bya aside sulfurike yakuwemo, aside phosphoric na aside asetiki. Kirwanya koga mu bisubizo bya chloride idafite aho ibohera. Kirwanya koga yangiritse muri chloride zimwe na zimwe zishyushye cyane kurusha icyuma cya nickel cyo hasi. Iki cyuma gifite ubushobozi bwo gukora neza no gusudira. Iki gikoresho kiboneka mu bipimo byose bisanzwe nka ASTM na EN, ariko hamwe n'itandukaniro. Imiterere yacyo igera kuri 370°C iri muri ASME II.
