◉I roto i te ao hou, kua noho te maitai kore waikura hei rauemi noa, he mea nui hoki e whakamahia whānuitia ana i roto i te hanganga, te mahi hanga me te oranga o ia rā. He maha ngā momo maitai kore waikura, tae atu ki ngā tauira noa pēnei i te 201, te 304 me te316.
Heoi, mō te hunga kāore e mārama ki ngā āhuatanga o te rauemi, he ngāwari te pōhēhē i ngā rerekētanga i waenga i ēnei tauira. Ka whakamāramahia e tēnei tuhinga ngā rerekētanga i waenga i te kowiri tira 201, 304 me te 316 hei āwhina i ngā kaipānui ki te mārama ake ki ngā tauira rerekē o ngā rauemi kowiri tira, me te whakarato i ētahi whakaaro mō te hoko kowiri tira.
◉Tuatahi, te rerekētanga o te hanganga matū
He mea nui te hanganga matū o te maitai kore waikura hei whakatau i tōna mahi me ōna āhuatanga.Kowiri tira 201, 304 me 316 he mārama ngā rerekētanga o te hanganga matū. Kei roto i te maitai kore waikura 201 he 17.5% -19.5% chromium, 3.5% -5.5% nickel, me te 0.1% -0.5% hauota, engari kāore he molybdenum.
Ko te maitai kore waikura 304, i tētahi atu taha, kei roto ko te 18%-20% chromium, 8%-10.5% nickel, ā, kāore he hauota, he molybdenum rānei. He rerekē, ko te maitai kore waikura 316 kei roto ko te 16%-18% chromium, 10%-14% nickel, me te 2%-3% molybdenum. Mai i te hanganga matū, he nui ake te ātete o te maitai kore waikura 316 ki te waikura me te ātete waikawa, he pai ake mō te whakamahi i roto i ētahi taiao motuhake i te maitai kore waikura 201 me te 304.
◉Tuarua, te rerekētanga o te ātete ki te waikura
He tohu nui te ātete ki te waikura o te maitai kore waikura. He pai te ātete o te maitai kore waikura 201 ki te nuinga o ngā waikawa waro, ngā waikawa kore waikura me ngā otinga tote i te pāmahana rūma, engari ka waikura i roto i te taiao kawakore kaha. He pai te ātete o te maitai kore waikura 304 ki te waikura, ā, he pai mō te nuinga o ngā taiao waikura whānui.
Ko te maitai kore waikura 316, i tētahi atu taha, he tino pai tōna ātete ki te waikura, inā koa i roto i ngā taiao waikawa me ngā āhuatanga pāmahana teitei, ā, he tino pai tōna ātete ki te waikura, e whakamahia ana i roto i ngā mahi matū, moana me ētahi atu mahi. Nō reira, i te wā e hoko ana i ngā rauemi maitai kore waikura, he mea nui kia whiriwhiria te tauira tika kia rite ki te whakamahinga motuhake o ngā taiao rerekē.
◉Tuatoru, te rerekētanga o ngā āhuatanga miihini
Kei roto i ngā āhuatanga ā-pūkaha o te kowiri tira ngā tohu pēnei i te kaha, te ngāwari me te pakeke. I te nuinga o te wā, he paku teitei ake te kaha o te kowiri tira 201 i te kowiri tira 304, engari he iti iho i te kowiri tira 316. He pai te ngāwari o te kowiri tira 201 me te 304, he ngāwari ki te tukatuka me te hanga, he pai mō ētahi o ngā whakaritenga mahi tukatuka rauemi o ngā wā teitei ake.
He kaha ake te kowiri tira 316, engari he pai hoki te ātete ki te kakahu me te kume, he pai mō te tu atu ki ngā taiao mahi kaha me te pāmahana tiketike. Nō reira, i te wā e whiriwhiri ana i ngā rauemi kowiri tira, me whiriwhiri e koe te mea tika kia rite ki ngā whakaritenga miihini me te whakamahinga o te taiao.
◉Tuawhā, te rerekētanga utu
He rerekētanga anō hoki te utu o te kowiri tira 201, 304 me te 316. I te nuinga o te wā, he iti ake te utu o te kowiri tira 201, he iti ake te utu. He nui te utu o te kowiri tira 304, engari nā te whānuitanga o ngā whakamahinga me te pai ake o te mahi whānui, ko tētahi tonu o ngā tauira kowiri tira tino noa i te mākete.
◉ He utu nui te kowiri tira 316 nā tōna ātete pai ki te waikura me ōna āhuatanga miihini, ā, he pai hoki mō ētahi mara motuhake e hiahia ana ki ngā āhuatanga rauemi teitei. Nō reira, i te hoko rauemi kowiri tira, me whai whakaaro koe ki ngā āhuatanga pēnei i te mahi rauemi me te tahua.
