ASTM A213, A269 904L ngongo kowiri tira kowiri tira i Haina
Ko te Alloy 904L he kowiri tira austenitic kore-pumau, teitei me te iti o te waro.Ka whakamahia nuitia i roto i nga tono karekau i te rawaka nga ahuatanga waikura o TP316/L me TP317/L.Ka tukuna ano e te koranu te ahua pai, te weldability, me te uaua.Ko te taapiri o te parahi ka hoatu he koranu 904L te waikura he pai ake i nga tira kowiri tira chrome nickel.Ko etahi tauira ko te atete ki te sulfuric, phosphoric, me te waikawa acetic.

Hangahanga
Ko te Alloy 904L he kore-aukume i roto i nga ahuatanga katoa, he tino pai te hanga me te weldability.Ko te hanganga austenitic ka hoatu i tenei karaehe te tino pakari, tae noa ki te wera tangihanga.
Nga tono Ahumahi
Tukatuka matū
Ko te nui o te chromium me te nickel ihirangi, me te taapiri o te molybdenum me te parahi, ka awhina i te 904L koranu ki te tu ki te sulfuric, phosphoric me te waikawa acetic.He tino whai hua tenei mo te hanga waikawa me nga maniua.
