Kupu Whakataki
Ko te karaehe 316 te karaehe paerewa e mau ana i te molybdenum, ko te tuarua o ngā maitai kore waikura austenitic te mea nui ki te 304. He pai ake ngā āhuatanga ātete waikura o te molybdenum ki te 316 i te karaehe 304, inā koa he nui ake te ātete ki te waikura poka me te kapiti i roto i ngā taiao pūhaumāota.
Ko te karaehe 316L, te putanga waro iti o te 316, ā, kāore e pāngia e te whakararuraru (te maturuturunga o te karāhe karāhe rohe witi). Nō reira, e whakamahia whānuitia ana i roto i ngā wāhanga whakarewa taumaha (neke atu i te 6mm). Kāore he rerekētanga utu nui i waenga i te maitai kore waikura 316 me te 316L.
Mā te hanganga austenitic ka tino pakari ēnei tohu, tae noa ki ngā pāmahana cryogenic.
Ki te whakatauritea ki ngā maitai kore waikura austenitic chromium-nickel, he nui ake te ngoki, te ahotea ki te pakaru, me te kaha kume o te maitai kore waikura 316L i ngā pāmahana teitei.

He aha pea i whiriwhiria ai tēnei hei utu mō te 316?
317L
He teitei ake te ātete ki ngā pūhaumāota i te 316L, engari he rite tonu te ātete ki te pakaru waikura ahotea.
Ātete ki te Waikura
He tino pai i roto i ngā momo taiao hau me ngā momo pāpāho waikura – he ātete ake i te 304. Ka taea te waikura i roto i ngā taiao hauota mahana, ā, ka pakaru te waikura ahotea i runga ake i te 60°C. E kiia ana he ātete ki te wai inu me te 1000mg/L o ngā pūhaumāota i ngā pāmahana taiao, ka heke ki te 500mg/L i te 60°C.
Ko te 316 te paerewa e kiia ana i te nuinga o te wā"maitai kore waikura kounga moana", engari kāore e ātete ki te wai moana mahana. I roto i te maha o ngā taiao moana, ka kitea te waikura o te mata o te 316, e kitea ana i te nuinga o te wā he parauri. He mea tino pā tēnei ki ngā kapiti me te āhua taratara o te mata.
Ātete Wera
He ātete pai ki te waikura i roto i te ratonga wā poto ki te 870°C, ā, kei te mahi tonu ki te 925°C. Te whakamahinga tonu o te 316 i roto i te 425-860°Kāore i te tūtohutia te whānuitanga C mēnā he mea nui te ātete waikura i muri mai. He ātete ake te karaehe 316L ki te maturuturunga carbide, ā, ka taea te whakamahi i roto i te whānuitanga pāmahana i runga ake nei. He kaha ake te karaehe 316H i ngā pāmahana teitei, ā, i ētahi wā ka whakamahia mō ngā tono hanganga me te pupuri pēhanga i ngā pāmahana neke atu i te 500.°C.
Te Maimoatanga Wera
Maimoatanga Wairewa (Whakamahana) – Whakamahanahia ki te 1010-1120°C, ā, ka tere te whakamatao. Kāore e taea te whakapakeke i ēnei momo mā te maimoatanga wera.
Whakarewa
He tino pai te āhua o te whakarewa mā ngā tikanga honohono me te ātete paerewa katoa, ahakoa he konganuku whakakī, he konganuku whakakī rānei. Ko ngā wāhanga taumaha kua whakarewaina i te Wāhanga 316 me whakamahana i muri i te whakarewa kia tino ātete ai ki te waikura. Kāore tēnei e hiahiatia mō te 316L.
Kāore e taea te whakarewa i te maitai kore waikura 316L mā te whakamahi i ngā tikanga whakarewa oxyacetylene.
Mīhini
Ka whakapakeke te maitai kore waikura 316L mēnā ka tere rawa te mīhini. Nā reira, me iti ngā tere me ngā tere whāngai pumau.
He māmā ake hoki te mīhini i te kowiri tira 316L i te kowiri tira 316 nā te mea he iti ake te ihirangi waro.
Te Mahi Wera me te Mahi Matao
Ka taea te mahi wera i te maitai kore waikura 316L mā te whakamahi i te nuinga o ngā tikanga mahi wera. Ko te pāmahana mahi wera tino pai me noho ki te awhe 1150-1260°C, ā, kaua rawa e iti iho i te 930°C. Me whakahaere te whakamahana i muri i te mahi kia nui ai te ātete ki te waikura.
Ko te nuinga o ngā mahi matao noa pēnei i te kutikuti, te tuhi me te tā ka taea te mahi i runga i te maitai kore waikura 316L. Me whakahaere te whakamahana i muri i te mahi hei tango i ngā ahotea o roto.
Te Whakamārō me te Whakamārō Mahi
Kāore te maitai kore waikura 316L e whakapakeketia i te wā e werahia ana. Ka taea te whakapakeke mā te mahi matao, ka hua ake ai hoki te kaha ake.
