He Tirohanga Whānui mō te Paipa Kowiri tira Alloy 430

430 Kowiri tiraisHe chromium ferritic, he chromium tika, he tohu kore-whakapakeke, e whakakotahi ana i te ātete pai ki te waikura me ngā āhuatanga hanga me ngā āhuatanga miihini whai hua. Nā tōna kaha ki te ātete i te whakaekenga waikawa hauota ka taea te whakamahi i roto i ngā tono matū motuhake, engari ko ngā wāhanga whakapaipai me ngā taputapu motuka te mea nui rawa atu o tana tono. He pai te ātete ki te waikura o te maitai 430 me te kaha hanga pai. He tino rite te 430 ki te maitai 439 he iti ake te chromium i te 16% te iti rawa o te ihirangi. He ātete ake te 430 ki te waikura me te waikura i te tohu 409. He tohu rongonui te 430 kāore e taea te whakapakeke, e whakamahia whānuitia ana i roto i ngā taiao o roto. Ka taea te hanga matao te 430 mā te piko, te kukume hohonu me te hanga totoro. He ngawari te mīhini i te 430, ā, he rite ki te maitai waro hanganga e hiahia ana kia rite ngā taunakitanga mō te taputapu, te tere tapahi me ngā whāngai tapahi. Ka taea te whakarewa i te 430 ahakoa me whakamahana pea.

Te Rerekētanga i waenganui i te 304 me te 430 Kowiri tira

Ko tētahi o ngā momo maitai kore-haumanu rongonui ko te 430. Ko te momo maitai kore-haumanu rongonui ko te 304. Kei roto i te hanganga 430 te rino me te iti iho i te 1% te nikara, tae atu ki te 18% te chromium, te silicon, te phosphorus, te whanariki, me te manganese. Me te 18% te chromium, te waro, te manganese, te silicon, te phosphorus, te whanariki, te hauota, me te rino, ko te 304 he 8% te nikara.

Ko te kaha tuku me te kaha kume iti rawa o ngā rauemi 304 he 215 MPa me te 505 MPa, ia, nā tēnei hanganga matū. Ko te kaha tuku me te kaha kume iti rawa o te rauemi 430 he 260 MPa me te 600 MPa. Ko te ira rewa o te 430 ka eke ki te 1510 nekehanga Celsius. He matotoru ake i te matū 430 te rauemi 304.
