He rauemi paipa rino te P235TR1, ā, ko tōna hanganga matū e tutuki ana i te paerewa EN 10216-1.te whare matū, ngā oko, te hanganga paipa me ngā mea noangā kaupapa hangarau mīhini.

E ai ki te paerewa, ko te hanganga matū o te P235TR1 kei roto ko te ihirangi waro (C) tae atu ki te 0.16%, te ihirangi silicon (Si) tae atu ki te 0.35%, te ihirangi manganese (Mn) i waenga i te 0.30-1.20%, te ihirangi phosphorus (P) me te whanariki (S). Ko te mōrahi o te ihirangi ko te 0.025%. Hei tāpiri, e ai ki ngā whakaritenga paerewa, tera pea kei roto i te hanganga o te P235TR1 he iti noa iho o ngā huānga pēnei i te chromium (Cr), te parahi (Cu), te nickel (Ni) me te niobium (Nb). Mā te whakahaere i ēnei hanganga matū ka taea te whakarite kia tika ngā āhuatanga miihini me te ātete ki te waikura o ngā paipa maitai P235TR1, kia pai ai te whakamahi i roto i ētahi tono ahumahi motuhake.

Mai i te tirohanga hanganga matū, ko te iti o te waro o P235TR1 ka āwhina i te whakapai ake i tōna āheinga whakarewa me te tukatuka, ā, ko te nui o te silicon me te manganese ka āwhina i te whakapai ake i tōna kaha me te ātete ki te waikura. Hei tāpiri, me whakahaere te nui o te phosphorus me te whanariki i ngā taumata iti hei whakarite i te parakore o te rauemi me te ngāwari ki te tukatuka. Ko te noho mai o ngā huānga iti pēnei i te chromium, te parahi, te nickel me te niobium ka pā pea ki ētahi āhuatanga o ngā paipa maitai, pēnei i te ātete wera, te ātete waikura rānei.

Haunga te hanganga matū, ko te tukanga hanga, ngā tikanga maimoatanga wera me ētahi atu tohu mahi ā-tinana o te paipa maitai P235TR1 he mea nui anō hoki e pā ana ki tōna mahi whakamutunga. I te nuinga o te wā, ko te hanganga matū o te paipa maitai P235TR1 tētahi o ngā mea matua hei whakarite kia tutuki i ngā whakaritenga o ngā paerewa e tika ana, ā, ka taea hoki te whakatutuki i ngā kaupapa hangarau motuhake.
