Te rahi o te ngongo maitai kore-tuitui me te rerekētanga e whakaaetia ana

Ngongo maitai waro (GB/8162-2008)

Ko tēnei momo paipa maitai hanganga ka whakarewaina mā te kaitahuri, mā te ahi tuwhera rānei, ko tōna rauemi mata matua he rino rewa me te maitai para, ko te nui o te whanariki me te whākawa i roto i te maitai he nui ake i tērā o te paipa maitai hanganga waro kounga teitei, ko te tikanga he whanariki ≤0.050%, ko te whākawa ≤0.045%. Ko te nui o ētahi atu huānga whakarewa, pērā i te chromium, te nickel me te parahi, i kawea mai ki roto i te maitai e ngā rauemi mata, kāore i te neke ake i te 0.30%. E ai ki ngā whakaritenga hanganga me te mahi, ko te tohu o tēnei momo paipa maitai hanganga e tohuhia ana e te tohu maitai Q195, Q215A, B, Q235A, B, C, D, Q255A, B, Q275 me ētahi atu.

Kia mōhio: Ko te "Q" te reta ā-reo Hainamana o te hua "qu", ā, whai muri ko te uara hua iti rawa (σ S) o te tohu, ā, whai muri ko te tohu e ai ki te ihirangi o ngā huānga poke (whanariki, whākawa) mai i te teitei ki te iti me ngā panonitanga o ngā huānga waro me te manganese, e whakarōpūtia ana kia whā ngā tohu A, B, C, D.

Ko tēnei momo paipa maitai hanganga te mea nui rawa atu, he whānui rawa te whakamahinga, he maha ake ngā whakamahinga hei pereti, hei kōtaha (porowhita, tapawhā, papatahi, mahi, awaawa, koki, me ētahi atu) me te kōtaha me te hanga paipa maitai whakarewa. Ko te nuinga o te whakamahinga he paipa maitai i roto i te awheawhe, i te piriti, i te kaipuke me ētahi atu hanganga whare me ngā paipa kawe wai whānui. Ko tēnei momo maitai ka whakamahia tika, kāore he maimoatanga wera.

Paipa maitai hanganga kaha teitei, he koranu iti (GB/T8162-2008)

Haunga te nui o te silicon, te manganese rānei, kei roto i ngā paipa maitai ētahi atu huānga e tika ana mō ngā rauemi o Haina. Pērā i te vanadium (V), te niobium (Nb), te titanium (Ti), te konumohe (Al), te molybdenum (Mo), te hauota (N), me ngā huānga whenua onge (RE). E ai ki te hanganga matū me ngā whakaritenga mahi, ko tōna taumata e tohuhia ana e Q295A, B, Q345A, B, C, D, E, Q390A, B, C, D, E, Q420A, B, C, D, E, Q460C, D, E me ētahi atu taumata maitai, ā, ko tōna tikanga he rite ki te paipa maitai hanganga waro.

Haunga te maitai taumata A me te B, me whai i te maitai taumata C, taumata D me te taumata E kia kotahi te iti rawa o ngā huānga iti o te witi kua parakoretia pērā i te V, Nb, Ti me te Al. Hei whakapai ake i te mahi a te maitai, ka taea hoki te tāpiri i te maitai taumata A, B ki tētahi o aua mea. Hei tāpiri, ko te ihirangi toenga o te Cr, Ni me te Cu he iti iho i te 0.30%. Ko te Q345A, B, C, D, E ngā taumata e whakaatu ana i tēnei momo maitai, i roto i ēnei ko te maitai taumata A, B e kiia ana ko te 16Mn; Me tāpiri neke atu i te kotahi te huānga iti ki te paipa maitai taumata C me runga ake, ā, me tāpiri kia kotahi te āhuatanga pānga pāmahana iti ki ōna āhuatanga miihini.

Ko te ōwehenga o tēnei momo paipa maitai hanganga ki te maitai hanganga waro. He kaha teitei, he pai te mahi whānui, he roa te ora mahi, he whānui te whānuitanga o te tono me te ohanga whakatairite. He whānui te whakamahinga i roto i ngā piriti, ngā kaipuke, ngā kohua, ngā waka me ngā hanganga whare nui.
