Rino:E pā ana ki te ihirangi waro i waenga i te rino me te waro i waenga i te 0.02% ki te 2.11%, nā te iti o te utu, te pono o te mahi, koinei te mea tino whānuitia te whakamahinga me te nui rawa o ngā rauemi whakarewa. Ko ngā hoahoa miihini kore-paerewa o te maitai tino whānuitia te whakamahinga ko: Q235, 45 # maitai, 40Cr, kowiri tira, kowiri tira pokepokea ai, ko te maitai puna me ētahi atu.
Te whakarōpūtanga o ngā maitai waro-iti, waro-waenga me te waro-tiketike:iti < waenga (0.25% ki te 0.6%) < teitei
Q235-A:He maitai waro iti te waro, he iti iho i te 0.2% te nui, e tohu ana ko te kaha whakaputa he 235MPa, he pai te kirihou, he kaha engari kāore i te ātete ki te pānga. Ko te hoahoa kore-paerewa te tikanga e whakamahia ana mō ngā wāhanga hanganga whakarewa.
45 # maitai:Ko te ihirangi waro o te maitai waro reo he 0.42 ~ 0.50%, ko ōna āhuatanga miihini, he pai te mahi tapahi, he ngoikore te mahi whakarewa. Ko te pakeke o te maitai 45 (te whakamātao + te whakamātao) i waenga i te HRC20 ~ HRC30, ko te pakeke o te tinei he HRC45 te tikanga e hiahiatia ana te pakeke i muri i te pumau kaha teitei.
40Cr:wātū i roto i te maitai hanganga koranu. He pai ngā āhuatanga hangarau i muri i te maimoatanga whakamahana, engari kāore i te pai te kaha whakarewa, he ngāwari ki te pakaru, ka taea te whakamahi hei hanga taputapu, tokotoko hono, toki, me ētahi atu, ka tineia te pakeke o te mata tae atu ki te HRC55.
Kowiri tira SUS304, SUS316:He rino waro iti te rahi, he ≤ 0.08% te nui o te waro. He pai te ātete ki te waikura, ngā āhuatanga miihini, te mahi wera me te piko, he paerewa SUS304 kore-aukume. Heoi, he maha ngā hua nā te wehenga o te hanganga whakarewa, te maimoatanga wera hē rānei me ētahi atu take, ka hua ake he aukume, pēnei i te hiahia mō te kore-aukume me whakauru ki ngā tuhi hangarau hei whakamārama. He kaha te ātete waikura SUS316 i te 304, inā koa i roto i te pāmahana teitei me ngā taiao kino. I tēnei wā, he maha ngā 316L kei te mākete, nā te iti o te nui o te waro, te pai o te mahi whakarewa, me te pai ake o te mahi tukatuka i te SUS316. Ko te pepa whakarewa i roto i te hoahoa kore-paerewa e whakamahia ana hei mahi i ngā wāhanga iti o te uhi o waho, ngā pūoko, me ētahi atu wāhanga paerewa o te nohoanga whakairi, ka taea te whakamahi i te akomanga pereti mō te hononga wāhanga.
Konumohe:Ko te pereti konumohe AL6061, AL7075, 7075 he pereti konumohe tino mārō, he nui ake te mārō i te 6061. Engari he nui ake te utu o te 7075 i te 6061. Ka taea te tukatuka i ēnei katoa mā te whakahāngaitanga anodic taiao, te whakahāngaitanga onepū, te whakahāngaitanga mārō, te whakakikorua nikara me ērā atu mea. Mā te tukatuka whānui i ngā wāhanga mā te whakahāngaitanga anodic taiao, ka taea te whakarite i te rahi o te whakaotinga. He pai ake te āhua o te whakahāngaitanga onepū, engari kāore e taea te kī he tino tika. Ki te hiahia koe kia rite te āhua o ngā wāhanga konumohe ki te maitai, ka taea te whakakikorua nikara ki ngā wāhanga. Ko ētahi wāhanga konumohe e pā tika ana ki ngā hua, pērā i te piri, te ātete pāmahana teitei me te iti, ka taea te whakaaro he whakakikorua Teflon ngā whakaritenga whakamarumaru.
Parahi:He parahi me te konutea te mea hanga, ā, he kaha te ātete ki te kakahu. Ko te parahi H65 he parahi 65% me te konutea 35%, nā te mea he pai te miihini, te hangarau, te mahi tukatuka wera me te makariri, ā, he koura te āhua, he kore-paerewa te āhua o ngā tono ahumahi, he nui ake te whakamahinga i roto i te hiahia mō te āhua ātete-kakahu o te wā.
Parahi papura:He parahi papura mō ngā monomer parahi, he ngoikore ake tōna pakari me tōna pakeke i te parahi, engari he pai ake te kawe wera. Ka whakamahia i roto i ngā whakaritenga kawe wera me te kawe hiko o ngā wā nui. Hei tauira, ko te wāhanga whakarewa taiaho o te wāhanga pane whakarewa.
