I te nuinga o te wā, he iti ake te wāhanga Nikel i roto i te maitai kore waikura o te reanga 201 i te maitai kore waikura o te reanga 304, nō reira ka nui ake te pakeke o te maitai kore waikura o te reanga 201, ka ngawari ake ki te waikura i te maitai kore waikura o te reanga 304, ā, kāore te mata i te kanapa pērā i te maitai kore waikura o te reanga 304. Heoi, he tino teitei te pakari o te maitai kore waikura o te reanga 201. Koinei tētahi o ngā kaha o te maitai kore waikura o te reanga 201.
He ngāwari te mahi i te maitai kore waikura o te karaehe 201 nā tōna āhua pai. Ka taea te mahi miihini pēnei i te tapahi, te whakarewa rānei i tēnei momo maitai kore waikura.
Kāore te maitai kore-aukume i te kounga 201, ā, he whānuitia te whakamahinga ki ngā hua e whakarei ake ana i te ātete o ngā kupu. Engari mō ngā hua e hiahia ana ki te aukume, me tāpiri he paparanga maitai kore-aukume i te kounga 410, 430 rānei ki te paparanga o waho o te maitai kore-aukume i te kounga 201.
3. He waikura te maitai kore waikura o te karaehe 201?
Nā te meamaitai kore waikura i te taumata 201He nui ake te hanganga konupora, ā, he iti ake te ōwehenga Nikel, ahakoa ko te āhuatanga whānui o te maitai kore waikura he ātete ki te waikura, he ngāwari ake te waikura o te maitai kore waikura o te reanga 201 i te maitai kore waikura o te reanga 304 me te 316. Nō reira, he iti ake te utu o te maitai kore waikura o te reanga 201. Heoi, ki te whakaritea ki ngā rauemi maitai kore waikura (kirihou, maitai, konumohe …), ko temaitai kore waikura i te taumata 201he kōwhiringa pai mō ngā hua e hiahia ana ki te roa me te ātete ki te mate pāwera.
4. He aha te pāmahana rewa o te maitai kore waikura i te taumata 201?
He rauemi ātete wera te kowiri tira. I roto i taua mea, ko te pāmahana rewa o te kowiri tira o te reanga 201 he 1400 – 1450 °C te teitei, he rite ki te pāmahana rewa o te kowiri tira o te reanga 304 engari he iti iho i ētahi atu kowiri tira.
5. He kawe hiko tō te maitai kore waikura o te reanga 201?
He pātai tēnei kua arohia, kua pātaihia hoki. Ae, ko te whakautu he āe, engari kāore i te nui. He rerekē ki te konganuku parahi 100% kawe hiko, ki ngā konganuku kawe hiko pai rānei pērā i te koura, te hiriwa, te rino, te konumohe. He tino iti te kawe hiko o te maitai kore waikura i te taumata 201. Nō reira, kāore te maitai kore waikura i roto i ngā rauemi e whakamahia ana mō te kawe hiko.
