I roto i ngā momo maitai kore waikura, ko ngā reanga 304, 304L, me te 304H ngā mea e whakamahia whānuitia ana. Ahakoa he āhua rite, he āhuatanga me ngā whakamahinga motuhake tō ia reanga.
Tau304 maitai kore waikuraKoia te mea tino whānuitia te whakamahinga, ā, he maha hoki ngā whakamahinga o ngā maitai kore waikura raupapa 300. Kei roto ko te 18-20% chromium me te 8-10.5% nickel, me te iti o te waro, te manganese, me te silicon. He tino pai te ātete ki te waikura o tēnei momo, ā, he pai hoki te āhua o te hanganga. He maha ngā whakamahinga e whakamahia ana i roto i ngā mahi pēnei i ngā taputapu kīhini, te tukatuka kai, me ngā whakapaipai whare.
Paipa kowiri tira 304LHe momo paipa maitai waro iti te momo 304, me te ihirangi waro mōrahi o te 0.03%. Mā tēnei ihirangi waro iti ka whakaitihia te maturuturunga o te carbide i te wā e whakarewahia ana, kia pai ai mō ngā mahi whakarewa. Mā te ihirangi waro iti ka whakaitihia hoki te mōrearea o te whakaaweawe, arā, te hanganga o ngā carbide chromium i ngā rohe kōpaka, ka arahi pea ki te waikura intergranular. He maha ngā wā ka whakamahia te 304L i roto i ngā mahi whakarewa, me ngā taiao e āwangawanga ana mō te mōrearea o te waikura, pērā i te tukatuka matū me ngā taputapu rongoā.
304H maitai kore waikuraHe putanga waro teitei ake tēnei o te karaehe 304, me te ihirangi waro kei waenga i te 0.04-0.10%. Nā te ihirangi waro teitei ake ka pai ake te kaha pāmahana teitei me te ātete ngoki. Nā tēnei ka pai te 304H mō ngā tono pāmahana teitei, pērā i ngā oko pēhanga, ngā whakawhiti wera, me ngā kohua ahumahi. Heoi, nā te ihirangi waro teitei ake ka ngawari ake te 304H ki te pāngia me te waikura intergranular, inā koa i roto i ngā tono whakarewa.
Hei whakarāpopototanga, ko te rerekētanga matua i waenga i ēnei tohu ko te nui o te waro me te pānga ki te whakarewa me ngā tono pāmahana teitei. Ko te tohu 304 te mea e whakamahia whānuitia ana, ā, ko te kaupapa whānui, ko te 304L ia te mea pai mō ngā tono whakarewa me ngā taiao e āwangawanga ana mō te waikura. He nui ake te nui o te waro o te 304H, ā, he pai mō ngā tono pāmahana teitei, engari me āta whakaaro ki tōna ngāwari ki te pāwera me te waikura intergranular. I te wā e whiriwhiri ana i waenga i ēnei tohu, he mea nui kia whakaarohia ngā whakaritenga motuhake o te tono, tae atu ki te taiao mahi, te pāmahana, me ngā hiahia whakarewa.
