He Tirohanga Whānui mō te Paipa Kowiri tira 904L

Ko te maitai kore waikura 904L he mea hanga ki te chromium, te nickel, te molybdenum me te parahi, ā, mā ēnei huānga ka pai ake te āhua o te maitai kore waikura 904L hei ārai i te waikura i roto i te waikawa whanariki waimeha nā te tāpiri o te parahi. E whakamahia whānuitia ana te 904L i roto i te taiao pēhanga teitei me te waikura, ina kore e pai te mahi a te 316L me te 317L. He nui te hanganga nickel o te 904L me te iti o te waro, mā te tāpiri i te koranu parahi ka pai ake tōna ātete ki te waikura. Ko te "L" i roto i te 904L e tohu ana i te waro iti, he maitai kore waikura Super Austenitic noa iho, ko ngā momo ōrite ko te DIN 1.4539, ā, ko te UNS N08904, he pai ake ngā āhuatanga o te 904L i ētahi atu maitai kore waikura austenitic.

Ngā Āhuatanga o ngā Paipa Kowiri tira 904L

He ātete tino pai ki te pakaru waikura i te ahotea nā te nui o te nikara i roto.

l Te waikura o te poka me te kapiti, te ātete ki te waikura intergranular.

Kāore te karaehe 904L i te ātete ki te waikawa hauota.

He tino pai te āhua hanga, te pakari me te ngāwari ki te whakarewa, nā te iti o te hanganga waro, ka taea te whakarewa mā te whakamahi i tētahi tikanga paerewa, kāore e taea te whakapakeke i te 904L mā te maimoatanga wera.

Kore-aukume, he kowiri tira Austenitic te 904L, nō reira, he āhuatanga hanganga Austenitic tōna.

Ātete Wera, he pai te ātete waikura o ngā maitai kowiri tira 904L. Heoi, ka hinga te pumau hanganga o tēnei kounga i ngā pāmahana teitei, inā koa neke atu i te 400°C.

Maimoatanga Wera, Ka taea te whakamahana i ngā maitai kore waikura karaehe 904L ki te wairewa i te 1090 ki te 1175°C, ā, muri iho ka tere te whakamatao. He pai te maimoatanga wera mō te whakapakeke i ēnei karaehe.
