Whakaahuatanga Poto:
Kei a mātou he waea maitai kore waikura 904L kounga teitei e tika ana mō ngā mahi ahumahi maha. Ako atu mō ngā utu me ngā kaiwhakarato.
Waea Kowiri tira 904L:
Ko te waea kowiri tira 904L he kowiri tira austenitic teitei-konumohe e mōhiotia ana mō tōna ātete tino pai ki te waikura, inā koa i roto i ngā taiao waikawa. He tino rapuhia tēnei waea kounga teitei mō ngā tono e hiahia ana kia kaha te ātete ki te pakaru, te waikura kapiti, me te pakaru waikura ahotea. Ki te whakaritea ki te 316L, he iti ake te ihirangi waro o te waea kowiri tira 904L, he 0.02% te iti, e āwhina ana ki te ārai i te waikura intergranular i te wā whakarewa. Hei tāpiri, ko te ihirangi molybdenum teitei ake i roto i te 904L ka whakarei ake i tōna ātete ki te pakaru me te waikura kapiti i puta mai i te hauota. Hei tāpiri, ko te whakaurunga o te parahi ki roto i te 904L ka whakarato i te ātete waikura whai hua puta noa i ngā kukū katoa o te waikawa whanariki, he mea tino pai mō te whakamahi i roto i ngā taiao tino waikura.
