Kodi P235GH ndi chinthu chiti? Kodi chikugwirizana ndi chinthu chiti ku China?

P235GH ndi chitoliro chachitsulo cha Fihekin ndi alloy chomwe chimagwira ntchito kutentha kwambiri, chomwe ndi chitsulo chomangidwa cha ku Germany chomwe chimagwira ntchito kutentha kwambiri. Chitoliro chachitsulo chosasunthika cha P235GH, EN10216-2 chikugwirizana ndi chitoliro chachitsulo chosasunthika cha dziko lonse cha 20G, 20MnG (GB 5310-2008).

Chitoliro chopanda msoko cha chitsulo cha P235GH nthawi zambiri chimasungunuka mu uvuni wamagetsi ndi chosinthira mpweya chomwe chimapangidwa pamwamba. Pazofunikira kwambiri, chimagwiritsa ntchito kuyeretsa kunja kwa ng'anjo, kusungunula ng'anjo ya vacuum induction kapena kusungunula vacuum kawiri, kusungunula electroslag kapena kutsuka vacuum, ndi kutentha.

Chitoliro chachitsulo chosasunthika cha P235GH, EN10216-2 ndi choyenera kupanga ziwiya zopanikizika ndi zida zina. Poyerekeza ndi chitsulo wamba, chitsulo chosungunuka cha P235GH chili ndi mphamvu komanso kulimba kwambiri, chimapindika bwino komanso chimawotcherera bwino, chimakhala ndi mphamvu ya mankhwala, chimagwirizana ndi zinthu zina, komanso chimagwirira ntchito bwino.

Kapangidwe ka makina a chitoliro chachitsulo cha P235GH: mphamvu yokoka σb350~480 MPa; mphamvu yotulutsa σs≥215 MPa; kutalika δ5≥ 25%; mphamvu yoyamwa mphamvu Akv≥47 J; Kulimba kwa Brinell ≤105~140 HB100

Kapangidwe ka mankhwala (gawo lalikulu, %) ya chitoliro chachitsulo cha 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.
