ASTM A213 Paerewa Paerewa
1.1 Kei roto i tenei whakakitenga te kohu rino ferrit me te austenitic maitai, te whakamahana nui, me nga ngongo whakawhiti wera, kua tohua nga Tohu T91, TP304, me etahi atu. Kua whakarārangihia enei tira ki nga Ripanga 1 me te 2.
1.2 Ko nga tohu kei roto te reta, H, i roto i to raatau tohu, he rereke nga whakaritenga mai i era o nga reanga rite kaore he reta, H. Ko enei whakaritenga rereke ka nui ake te kaha o te ngokingoki atu i te nuinga o te waa ka taea i roto i nga reanga rite kaore enei whakaritenga rereke.
1.3 Ko nga rahi me te matotoru o nga ngongo e rite ana ki tenei whakaritenga ko te 1/8 inihi [3.2 mm] te whanui o roto ki te 5 inihi [127 mm] te diameter o waho me te 0.015 ki te 0.500 inihi [0.4 ki te 12.7 mm], kei roto, i roto i te matotoru pakitara iti ranei, ki te tohua i roto i te ota, toharite matotoru pakitara.Ko nga ngongo me etahi atu diameter ka taea te whakawhiwhi, mena ka tutuki enei ngongo ki nga whakaritenga katoa o tenei tohu.
1.4 Ko nga uara e kiia ana i roto i nga waeine SI, i nga waeine inihi-pauna ranei me whakaaro motuhake hei paerewa.I roto i te tuhinga, ka whakaatuhia nga wae SI i roto i nga taiapa.Ko nga uara e kiia ana i ia punaha kaore pea i te tino rite;no reira, me whakamahi takitahi ia punaha i tetahi atu.Ko te whakakotahi i nga uara mai i nga punaha e rua ka kore e rite ki te paerewa.Ko nga waeine inihi-pauna ka pa ki te kore e tohua te tohu "M" o tenei tohu ki te ota.
TAPA 1 Nga Tepe Tito Matū, %A, mo te maitai Alloy itiA Morahi, mena ka tohua te awhe, te iti ranei.Ki te puta nga porotiti (…) ki tenei ripanga, kaore he whakaritenga, kaore hoki e tika kia whakatauhia, kia ripoatahia te tātaritanga mo te huānga.
B Ka whakaaetia te tono T2 me T12 me te ihirangi whanariki o te 0.045 max..
C Tërä, hei whakakapi i te iti rawa o tënei öwehenga, me 275 HV te pakeke o te rauemi i roto i te ahua pakeke, kua tautuhia i muri i te whakamaarama me te whakamatao ki te pāmahana rūma engari i mua i te whakamahana.Ka mahia nga whakamatautau pakeke i waenga i te matotoru o te hua.Ko te auau o te whakamatautau pakeke kia rua nga tauira o te hua mo ia rota maimoatanga wera me te whakaatu i nga hua whakamatautau pakeke i runga i te ripoata whakamatautau rauemi.
