Raupapa 200: maitai kore waikura austenitic chromium-nickel-manganese
Raupapa 300: maitai kore waikura austenitic chromium-nickel
301: He pai te ngāwari, e whakamahia ana mō ngā hua i hangaia. Ka taea hoki te whakapakeke mā te tere o te mīhini. He pai te kaha ki te whakarewa. He pai ake te ātete ki te kakahu me te kaha o te ngenge i te kowiri tira 304.
302: ātete ki te waikura me te 304, nā te nui o te waro i roto, ā, he kaha ake.
302B: He momo maitai kore waikura tēnei, he nui te ihirangi silicon, ā, he ātete nui ki te waikura pāmahana teitei.
303: Mā te tāpiri i tētahi iti o te whanariki me te whākōkī kia māmā ake ai te mahi miihini.
303Se: E whakamahia ana hoki hei hanga i ngā wāhanga mīhini e hiahia ana kia wera te upoko, nā te mea he pai te mahi wera o tēnei maitai kore waikura i raro i ēnei āhuatanga.
304: 18/8 kowiri tira. Kaute GB 0Cr18Ni9. 309: he pai ake te ātete ki te pāmahana i te 304.
304L: He momo maitai kore waikura 304 he iti iho te ihirangi waro, e whakamahia ana i ngā wāhi e hiahiatia ana te whakarewa. Mā te iti o te ihirangi waro ka whakaitihia te maturuturunga o ngā waro i roto i te rohe e pāngia ana e te wera e tata ana ki te whakarewa, ka arahi pea tēnei ki te waikura intergranular (te memeha o te whakarewa) o te maitai kore waikura i ētahi taiao.
304N: He maitai kore waikura kei roto te hauota, e tāpirihia ana hei whakanui ake i te kaha o te maitai.
305 me te 384: He nui te nikara kei roto, he iti te tere whakapakeketanga mahi, ā, he pai mō ngā momo mahi maha e hiahia ana kia ngāwari te hanga matao.
308: Whakamahia hei hanga rākau whakarewa.
309, 310, 314 me te 330: he nui te ihirangi nikara me te konukōmiuma, hei whakapai ake i te ātete waikura o te maitai i ngā pāmahana teitei me te kaha ngoki. Ahakoa he momo rerekē te 30S5 me te 310S o te maitai kore waikura 309 me te 310, ko te rerekētanga he iti ake te ihirangi waro, kia iti ai ngā waro ka puta tata ki te whakarewa. He tino teitei te ātete o te maitai kore waikura 330 ki te waro me te ātete ki te ru wera.
316 me te 317: kei roto konumohe, nō reira he pai ake te ātete ki te waikura i roto i ngā taiao ahumahi moana me te matū i te maitai kore waikura 304. I roto i ēnei, te momo 316 kowiri tiraKo ngā momo ko te maitai kore waikura waro-iti 316L, te maitai kore waikura kaha-teitei 316N kei roto te hauota, me te nui o te whanariki o te maitai kore waikura miihini-kore utu 316F.
321, 347 me te 348: he titanium, he niobium me te tantalum, he kowiri tira niobium kua whakapūmautia, he pai mō te whakamahi i ngā pāmahana teitei i roto i ngā wāhanga whakarewa. Ko te 348 he momo kowiri tira e tika ana mō te umanga mana karihi, ko te tantalum me te nui o te keri me te herenga.
Raupapa 400: maitai kore waikura ferritic me te martensitic
408: He ātete wera pai, he ātete waikura ngoikore, 11% Cr, 8% Ni.
409: ko te momo iti rawa te utu (Peretania me Amerika), e whakamahia ana hei paipa putanga hau o te motuka, he maitai kore waikura ferritic (maitai konupora)
410: martensitic (te maitai chromium kaha-teitei), he ātete pai ki te kakahu, he ātete iti ki te waikura. 416: mā te whanariki tāpiri ka pai ake te ngāwari o te miihini o te rauemi.
420: He maitai martensitic "tohu taputapu tapahi", he rite ki te maitai Brinell teitei-chromium, te maitai kowiri tira tuatahi. Ka whakamahia hoki mō ngā maripi pokanga, ā, ka taea te hanga kia kanapa rawa.
430He kowiri tira ferritic, he mea whakapaipai, hei tauira, mō ngā taputapu motuka. He pai te āhua hanga, engari he ngoikore te ātete ki te pāmahana me te waikura.
440: he maitai mata tapahi kaha-teitei, he nui ake te ihirangi waro, ā, i muri i te whakamahana tika ka taea te whiwhi i te kaha whakaputa teitei, ka taea te pakeke ki te 58HRC, nō te maitai kowiri tira tino pakari. Ko te tauira tono tino noa ko te "mata heu". E toru ngā momo e whakamahia whānuitia ana: 440A, 440B, 440C, me te 440F (momo ngāwari ki te mīhini).
Raupapa 500: Rino koranu chromium ātete-wera
Raupapa 600: Kowiri tira whakapakeke-whakaheke Martensitic
630: Ko te momo maitai kore waikura whakapakeke-pūngao e whakamahia whānuitia ana, e kiia ana ko te 17-4; 17% Cr, 4% Ni.
