Ko ASTM, e mōhiotia ana ko te American Society for Testing and Materials, he whakahaere paerewa whai mana o te ao e arotahi ana ki te whakawhanake me te whakaputa i ngā paerewa mō ngā momo ahumahi. Ka whakaratohia e ēnei paerewa ngā tikanga whakamātautau ōrite, ngā whakaritenga me ngā aratohu mō te ahumahi o Amerika. Kua hangaia ēnei paerewa hei whakarite i te kounga, te mahi, me te haumaru o ngā hua me ngā rauemi, me te whakahaere i te whakahaere maeneene o te hokohoko o te ao.
He whānui te kanorau me te whānuitanga o ngā paerewa ASTM, ā, e kapi ana i te whānuitanga o ngā mara tae atu ki, engari kāore i te herea ki, te pūtaiao rauemi, te hangarau hanga, te matū, te hangarau hiko, me te hangarau mīhini. Ka kapi ngā paerewa ASTM i ngā mea katoa mai i te whakamātautau me te aromatawai i ngā rauemi mata ki ngā whakaritenga me ngā aratohu i te wā hoahoa hua, te whakaputa, me te whakamahi.
ASTM A36/A36M:
He whakatakotoranga paerewa mō te maitai e kapi ana i ngā whakaritenga mō te maitai waro hanganga mō te hanganga, te hanga, me ētahi atu tono hangarau.
Pereti Rino A36Ngā Paerewa Whakatinanatanga
Paerewa whakatinanatanga ASTM A36/A36M-03a, (he rite ki te waehere ASME)
Pereti A36whakamahi
E pā ana tēnei paerewa ki ngā piriti me ngā whare he hanganga kua whakapūmautia, kua whakapūmautia, kua whakarewahia hoki, tae atu ki ngā wāhanga maitai hanganga whānui, ngā pereti me ngā pae maitai waro kounga teitei. Ko te hua o te pereti maitai A36 he tata ki te 240MP, ā, ka piki ake me te matotoru o te rauemi kia heke ai te uara hua, nā te ihirangi waro taurite, ka pai ake te mahi whānui, te kaha, te kirihou me te whakarewa me ētahi atu āhuatanga hei whiwhi i te ōritenga pai ake, ko te mea tino whānui te whakamahi.
Te hanganga matū o te pereti maitai A36:
C: ≤ 0.25, Si ≤ 0.40, Mn: ≤ 0.80-1.20, P ≤ 0.04, S: ≤ 0.05, Cu ≥ 0.20 (ina whakamahia te maitai kei roto te parahi).
Ngā āhuatanga miihini:
Kaha whakaputa: ≥250.
Kaha kume: 400-550.
Te roa: ≥20.
He rite te paerewa ā-motu me te rauemi A36 ki te Q235.
