Vuam
Vuam 254 smo ™ stainless hlau qib yuav tsum muab cov khoom siv cov khoom siv; Yog tsis muaj nws, tsis muaj zog zog tau txais. Cov tub lim hlau ua haujlwm xws li AWS A5.14 ernicrmo-3 thiab alloy 625 yog pom zoo. Cov hluav taws xob siv hauv cov txheej txheem yuav tsum phim rau AWS A5.11 ENICRMO-12.
Ib qho tseem ceeb
Annealing ntawm cov khoom no yuav tsum tau ua ntawm 1149-1204℃(2100-2200℃f), ua raws li los ntawm dej quenching.
Kev puas ntsoog
Stainless Hlau Qib 254 SmO ™ tsis teb rau kev kho cua sov. Hardening tsuas yog ua tau los ntawm kev txo tus mob khaub thuas.
