SS904L AISI 904L Kowiri tira (UNS N08904)
Whakataki Hua
Ko te AISI 904L he kowiri tira (UNS N08904) he kowiri tira austenitic teitei. Ka whakatauritea ki te 316L, he iti ake te waro (C) o te SS904L, he teitei ake te ihirangi chromium (Cr), me te tata ki te rua o nga ihirangi nickel (Ni) me te molybdenum (Mo) o316L, na te mea ka nui ake te parenga o te waikura i te pāmahana teitei, te aukati rua, me te aukati ki te whakaheke waikawa (hei tauira, te waikawa pungatara). Ka taea e Nitrogen (N) te whakaheke i te reanga o te chromium carbide precipitation, na reira ka whakaiti i te aro o te sensitization, ka pai ake hoki te aukati ki te rua me te waikura kapiti na te chlorides. Ina koa ko te taapiri o te parahi (Cu) ka whai hua mo nga kohinga katoa o te waikawa pungatara.
He pai ake te mahi a Alloy 904L i era atu tira kowiri tira austenitic na te kaha o te whakakotahitanga o te nickel me te molybdenum. Ko te karaehe he kore-aukume i roto i nga ahuatanga katoa, he tino pai te hanga me te weldability. Ko te hanganga austenitic ka tino kaha ki tenei karaehe, tae noa ki te wera tangihanga. Karekau he mate o te waikura intercrystalline i runga i te whakamahana, i te whakapiri ranei na te iti o te waro. Ko tona pāmahana ratonga teitei kei te 450°C. He tino whai hua tenei karaehe mo te whakahaere me nga taputapu ngongo ngongo kaore e pai te 316 me te 317L.
Ko te Alloy 904L i hangaia i te tuatahi ki te tu ki nga taiao kei roto te waikawa pungatara waimeha. He pai hoki te aukati ki etahi atu waikawa pararopi penei i te waikawa phosphoric wera tae atu ki te nuinga o nga waikawa waro.
Ko te Alloy 904L he ngawari te paihere me te tukatuka e nga tikanga hanga toa.
Ko te 904L kowiri tira (SS904L) e whakamahia ana i roto i te hinu, te matū, te tongi, nga pourewa whanaketanga moana, nga taika, nga paipa me nga ngongo me nga whakawhiti wera. Ka whakamahia ano e Rolex me etahi atu kaihanga mataaratanga ki te hanga mataaratanga
