Austenite Kowiri tira
Te Whakamahana Teitei
◆904L e kore e taea e anake te whakaoti i te waikura whānui o te waikawa pungatara, waikawa ūkuikui me te waikawa acetic, engari ano hoki te whakaoti rapanga o te waikura poka pūhaumāota, waikura kapiti me te waikura ahotea.
◆253Ma (S30815) Ko te wera-ātete parakore austenitic kowiri tira whakawhanakehia i runga i te pūtake o 21Cr-11Ni kowiri tira i roto i N alloying me te tāpiri huānga whenua onge Ce. Ka whakamahia te nuinga ki te hanga papa.
Ko te ◆254SMo (F44 / S31254) he kowiri tira austenitic tino teitei, he maha nga wa e whakamahia ana hei whakakapi mo te nickel teitei me te titanium alloys. Kei te whakamahia te nuinga i roto i te maha o nga tono kino penei i nga tikanga matū me te petrochemical me nga otinga hauota.
Ko te ◆Al-6XN(N08367) he pai mo nga papua, nga paera, nga flanges me nga punaha paipa o te hinu me te hau, te matū me te hiko hiko.
