He aha te rauemi o P235GH? He aha te rauemi e rite ana ki Haina?

He paipa maitai Fihekin me te koranu te P235GH, he maitai hanganga pāmahana-teitei nō Tiamana. Ko te paipa maitai kore-pēhanga P235GH, EN10216-2 e rite ana ki te paerewa ā-motu 20G, 20MnG (GB 5310-2008 paipa maitai kore-pēhanga teitei).

Ko te paipa maitai koranu P235GH he mea whakarewa i roto i te oumu pewa hiko me te kaitahuri hau-runga. Mō ngā whakaritenga teitei, ka whakamahia te whakamahine i waho o te oumu, te whakarewa oumu whakapūmau korehau, te whakarewa korehau takirua rānei, te whakarewa anō i te para hiko, te maimoatanga korehau rānei, me te maimoatanga wera.

He pai te paipa maitai kore-pēhanga P235GH, EN10216-2 mō te hanga oko pēhanga me ngā wāhanga taputapu. Ki te whakaritea ki te maitai noa, he kaha ake, he pakari ake te maitai koranu P235GH, he pai ake te piko makariri me te pai ake te whakarewa, ngā āhuatanga matū, te hototahi koiora, ngā āhuatanga ā-tinana me te pai ake o te tukanga.

Ngā āhuatanga hangarau o te paipa maitai koranu P235GH: te kaha kume σb350~480 MPa; te kaha hua σs≥215 MPa; te roa δ5≥ 25%; te kaha mimiti pānga Akv≥47 J; te pakeketanga o Brinell ≤105~140 HB100

Te hanganga matū (wāhanga papatipu, %) o te paipa maitai koranu P235GH: ≤0.16 Si; 0.60~1.20 Mn; ≤0.025 Cr; ≤0.30 Ni; ≤0.30 Cu; ≤0.08 Mo; ≤0.02 V; ≤0.02 Nb; ≤0.012 N; P; ≤0.010 S; ≤0.30, ≤0.020 Al; C; ≤0.35, ≤0.03 Ti.
