Ko te AISI 904L kowiri tira, AISI 904L (WNR1.4539) ASTM A 249, N08904, X1NiCrMoCu25-20-5 rānei, he kowiri tira austenitic teitei te konukōre. Ki te whakaritea ki te 316L, he iti ake te ihirangi waro (C) o te SS904L, he nui ake te ihirangi chromium (Cr), ā, tata ki te rua te nui o te ihirangi nikara (Ni) me te molibdenum (Mo) o te 316L, ka nui ake te pāmahana...
Kei roto i te 904L (N08904,, 14539) te kowiri tira austenitic tino nui, he 19.0-21.0% te chromium, 24.0-26.0% te nikara, me te 4.5% te molibdenum. Ko te 904L te kowiri tira austenitic tino nui, he kowiri tira austenitic iti-waro, he nikara teitei, he molibdenum te nui o te nikara, he rauemi motuhake i whakaurua mai e te kamupene H·S Wīwī. He pai tōna kaha ki te huri i te whakahohenga-whakakore, he ātete pai ki te waikura, he pai tōna ātete ki te waikura i roto i ngā waikawa kore-waikura pērā i te waikawa whanariki, te waikawa acetic, te waikawa formic, te waikawa phosphoric, he pai tōna ātete ki te poka i roto i ngā pāpāho ion chloride kūpapa, ā, he pai tōna ātete ki te waikura kapiti me te waikura ahotea. He pai mō ngā kukū rerekē o te waikawa whanariki i raro i te 70°C, ā, he pai tōna ātete ki te waikura i roto i te waikawa acetic o tetahi kukū me tetahi pāmahana i raro i te pēhanga noa, me te waikawa whakaranu o te waikawa formic me te waikawa acetic.
Ko te maitai kore waikura AISI 904L he maitai kore waikura austenitic teitei-konumohe, he iti rawa te ihirangi waro. Mā te whakakotahitanga o te chromium, te nickel, te molybdenum me te parahi teitei ka pai te ātete ki te waikura. Mā te tāpiri o te parahi ka kaha te ātete ki te waikawa, ka taea te ātete ki ngā waikawa waro me ngā waikawa kore-waro, inā koa te waikura kapiti hauota me te pakaru waikura ahotea, kāore e ngāwari ki te whai ira waikura me ngā kapiti, ā, he kaha te ātete ki te poka. He pai te ātete waikura o te AISI 904L i roto i te waikawa whanariki waimeha. He maitai te konumohe e tika ana mō te waimeha kaha waikawa whanariki waimeha. He ātete hoki ki te wai moana, he pai te miihini me te whakarewa, ā, he whānuitia te whakamahinga i roto i te hanga, te matū, te hauora me ētahi atu ahumahi.
Ko te maitai kore waikura AISI 904L e whakamahia whānuitia ana i roto i ngā tauhohenga i roto i ngā taputapu hinu me te matū; ngā taputapu rokiroki me te kawe waikawa whanariki, pērā i ngā whakawhiti wera; ngā taputapu whakakore hau haurehu i roto i ngā tipu hiko, pērā i ngā pourewa, ngā haurehu, ngā arai, ngā wāhanga o roto, ngā rehu, ngā pā, me ētahi atu i roto i ngā pūnaha maimoatanga waikawa waro; ngā taputapu maimoatanga wai moana, pērā i ngā whakawhiti wera wai moana; ngā taputapu ahumahi pepa, ngā taputapu waikawa whanariki, ngā taputapu waikawa hauota; ngā taputapu matū, ngā oko pēhanga, ngā taputapu kai pērā i te hanga waikawa me ngā ahumahi rongoā.
