Whakaahuatanga o te Paipa Kowiri tira 304L
Paipa kowiri tira 304L--S30403 (Amerika AISI, ASTM) 304L e rite ana ki te tohu Haina 00Cr19Ni10.
Ko te maitai kore waikura 304L, e mōhiotia ana ko te maitai kore waro-iti rawa, he rauemi maitai kore waikura maha-whakamahinga e whakamahia whānuitia ana i roto i te hanga taputapu me ngā wāhanga e hiahia ana ki te mahi whānui pai (ātete ki te waikura me te kaha ki te hanga). Ko te iti o te ihirangi waro ka whakaiti i te maturuturunga o ngā waro i roto i te rohe e pāngia ana e te wera e tata ana ki te whakarewa, ā, ko te maturuturunga o ngā waro ka puta te waikura intergranular (te memeha o te whakarewa) o te maitai kore waikura i roto i ētahi taiao.
I raro i ngā āhuatanga noa, he rite te ātete waikura o te paipa maitai kore waikura 304L ki te maitai 304, engari i muri i te whakarewanga, i te ahotea rānei, he tino pai tōna ātete ki te waikura intergranular. Ki te kore he maimoatanga wera, ka taea hoki te pupuri i te ātete waikura pai, ā, ka whakamahia whānuitia i raro i te 400 nekehanga (kore-aukume, pāmahana whakahaere -196 nekehanga Celsius ki te 800 nekehanga Celsius).
E whakamahia ana te maitai kore waikura 304L i roto i ngā mīhini o waho, ngā rauemi hanga whare, ngā wāhanga ātete-wera me ngā wāhanga he uaua te maimoatanga wera i roto i ngā ahumahi matū, waro me te hinu e hiahiatia ana te ātete ki te waikura intergranular.
