904L Kowiri tira Paipa Taonga

l He pai te atete ki te pakaru o te waikura na te nui o te ihirangi nickel.

l Te waikura rua me te kapiti, te aukati waikura intergranular.

l Ko te karaehe 904L he iti ake te atete ki te waikawa nitric.

l He tino pai te ahua, te uaua me te weldability, na te iti o te hanganga waro, ka taea te paihere ma te whakamahi i tetahi tikanga paerewa, kaore e taea e te 904L te whakapakeke i te maimoatanga wera.

l Kore-aukume, 904L he kowiri tira Austenitic, no reira kei a 904L nga ahuatanga hanganga Austenitic.

l Heat Resistance, Grade 904L kowiri tira whakahere pai ātete hāoratanga. Heoi, ka hinga te hanganga o tenei karaehe i nga wera nui, ina koa kei runga ake i te 400°C.

l Heat Treatment, Grade 904L kowiri tira e taea te otinga wera-tukinotia i 1090 ki 1175 ° C, whai i te mātao tere. He pai te maimoatanga wera mo te whakapakeke i enei tohu.
