ASTM A213, A269 904L ibyuma bidafite ingese byashizwe mu Bushinwa
Alloy 904L nicyuma kidahamye, cyinshi cya austenitike idafite ibyuma bidafite karubone.Irakoreshwa cyane mubisabwa aho imitungo ya ruswa ya TP316 / L na TP317 / L idahagije.Amavuta atanga kandi uburyo bwiza, gusudira, no gukomera.Kwiyongera k'umuringa bitanga ibinyobwa 904L byangirika byangirika biruta ibyuma bisanzwe bya chrome nikel bitagira umuyonga.Ingero zirimo kurwanya aside sulfurike, fosifori, na acide acike.

Ibihimbano
Alloy 904L ntabwo ari magnetique mubihe byose kandi ifite uburyo bwiza bwo gusudira.Imiterere ya austenitis nayo itanga iki cyiciro ubukana buhebuje, ndetse no munsi yubushyuhe bwa cryogenic.
Inganda zikoreshwa
Uburyo bwa Shimi
Chromium nyinshi hamwe na nikel, hamwe no kongeramo molybdenum n'umuringa, bifasha alloy 904L guhagarara kuri acide sulfurike, fosifori na acetike.Ibi ni ingirakamaro cyane cyane mu gukora acide n'ifumbire.
Andika ubutumwa bwawe hano hanyuma utwohereze
