Kupu Whakataki
He maitai kowiri tira ngā maitai kowiri tira. E whā ngā rōpū o ēnei maitai, arā, ko ngā maitai martensitic, austenitic, ferritic me ngā maitai whakapakeke-wai. Ka hangaia ēnei rōpū i runga i te hanganga tioata o ngā maitai kowiri tira.
He nui ake te chromium i roto i ngā maitai kore waikura i ērā atu maitai, nō reira he pai te ātete ki te waikura. Ko te nuinga o ngā maitai kore waikura he tata ki te 10% te chromium.
Ko te maitai kore waikura taumata 2205 he maitai kore waikura takirua, ā, mā te hoahoa ka taea te whakakotahi i te ātete pai ake ki te pakaru, te kaha teitei, te waikura ahotea, te waikura kapiti me te ngatata. Ka ātete te maitai kore waikura taumata 2205 ki te waikura ahotea whanariki me ngā taiao hauota.

Te Hanga me te Maimoatanga Wera
Te whakamahana
Ka whakawerahia te maitai kore waikura karaehe 2205 i te 1020-1070°C (1868-1958°F) kātahi ka tineia ki te wai.
Te Mahi Wera
Ka mahi wera te maitai kore waikura karaehe 2205 i te awhe pāmahana 954-1149°C (1750-2100°F). E taunakihia ana kia mahi wera tēnei maitai kore waikura karaehe i raro i te pāmahana rūma i ngā wā katoa e taea ai.
Whakarewa
Ko ngā tikanga whakarewa e taunakitia ana mō te maitai kore waikura taumata 2205 ko te SMAW, MIG, TIG me ngā tikanga hiko hipoki ā-ringa. I te wā o te tukanga whakarewa, me whakamatao te rauemi i raro i te 149°C (300°F) i waenganui i ngā haerenga, ā, me karo te whakamahana i mua i te wāhanga whakarewa. Me whakamahi i ngā whakaurunga wera iti mō te whakarewa maitai kore waikura taumata 2205.
Te hanga
He uaua te hanga i te maitai kore waikura karaehe 2205 nā tōna kaha nui me tōna tere whakapakeketanga mahi.
Te āheinga ki te mīhini
Ka taea te mīhini i te maitai kore waikura karaehe 2205 mā te whakamahi i te taputapu carbide, i te taputapu tere-rahi rānei. Ka whakaitihia te tere mā te 20% pea ina whakamahia te taputapu carbide.
