Stainless hlau 253 MA
Stainless 253 MA yog ib qho austenitic tshav kub resistant alloy nrog siab zog thiab zoo heev oxidation kuj. 253 MA tswj nws cov khoom siv hluav taws xob los ntawm kev tswj xyuas qib siab ntawm micro alloy ntxiv. Kev siv cov hlau tsis tshua muaj hauv ntiaj teb ua ke nrog silicon muab kev tiv thaiv oxidation zoo txog 2000 ° F. Nitrogen, carbon thiab dispersion ntawm lub ntiaj teb tsis tshua muaj thiab alkali hlau oxides ua ke los muab cov creep rupture zog piv rau cov nickel puag alloys. Ntau yam khoom siv uas xav tau lub zog siab ntawm qhov kub siab xws li cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab cov khoom siv hauv qhov cub yog cov kev siv rau 253 MA.
