E whakaatu ana te maitai kore waikura 301 i te āhuatanga whakapakeke mahi i te wā e rerekē ana te āhua, ā, e whakamahia ana i ngā wā maha e hiahia ana kia kaha te mahi.
Ko te maitai kore waikura 302 he momo kē atu i te maitai kore waikura 304, he nui ake te waro. Ka taea te whakapiki ake i tōna kaha mā te huri matao.
Ko te 302B hekowiri tira me te ihirangi silicon teitei, he ātete nui ki te waikura i te pāmahana tiketike.
Ko te 303 me te 303Se he maitai kore-whakairoiro e tapahia noatia ana, kei roto ko te whanariki me te selenium, e whakamahia ana mō ngā wā e ngawari ai te tapahi me te kanapa teitei.
E whakamahia ana hoki te maitai kore waikura 303Se hei hanga i ngā wāhanga e hiahia ana kia wera te wera, nā te mea he pai te kaha o tēnei maitai kore waikura ki te wera i raro i ēnei āhuatanga.
Ko te 304 he momo maitai kore waikura whānui, e whakamahia whānuitia ana hei hanga taputapu me ngā wāhanga e hiahia ana ki te mahi whānui pai (ātete ki te waikura me te ngāwari ki te hanga).
Ko te 304L he momo rerekē o te maitai kore waikura 304 he iti te ihirangi waro, e whakamahia ana mō ngā wā e hiahiatia ana he whakarewa. Nā te iti o te ihirangi waro ka whakaitihia te maturuturunga o ngā warowaiha ki te rohe e pāngia ana e te wera tata ki te whakarewa, ā, ko te maturuturunga o ngā warowaiha ka puta te waikura intergranular (te waikura whakarewa) o te maitai kore waikura i ētahi taiao.
He momo maitai kore waikura te 304N kei roto te hauota. Ko te kaupapa o te tāpiri hauota he whakapai ake i te kaha o te maitai.
