Kodi P235GH ndi chiyani? Kodi chikugwirizana ndi chiyani ku China?

P235GH ndi ntchito yotentha kwambiri ya Fihekin ndi chitoliro chachitsulo cha alloy, chomwe ndi chitsulo cha German chotentha kwambiri. P235GH, EN10216-2 kuthamanga opanda zitsulo chitoliro limafanana ndi dziko muyezo 20G, 20MnG (GB 5310-2008 mkulu-anzanu kukatentha kukatentha zitsulo chitoliro).

P235GH alloy steel chitoliro chosasunthika chitoliro nthawi zambiri chimasungunuka mu ng'anjo yamagetsi yamagetsi ndi chosinthira chowombera mpweya wabwino kwambiri. Pazofunika kwambiri, imatengera kuyenga kunja kwa ng'anjo, kusungunula ng'anjo ya vacuum kapena kusungunula vacuum kawiri, electroslag remelting kapena vacuum chithandizo, ndi chithandizo cha kutentha.

P235GH, EN10216-2 chitoliro chachitsulo chosasunthika ndi choyenera kupanga zombo zoponderezedwa ndi zida. Poyerekeza ndi chitsulo wamba, P235GH aloyi chitsulo ali ndi mphamvu apamwamba ndi kulimba, ozizira kupinda ntchito ndi kuwotcherera, katundu mankhwala, biocompatibility, katundu thupi ndi ntchito ndondomeko.

Makina amakina a P235GH aloyi chitsulo chitoliro: mphamvu yolimba σb350 ~ 480 MPa; zokolola mphamvu σs≥215 MPa; elongation δ5≥ 25%; mphamvu mayamwidwe mphamvu Akv≥47 J; Brinell kuuma ≤105~140 HB100

Mankhwala opangidwa ndi mankhwala (kachigawo kakang'ono,%) a P235GH alloy steel pipe: ≤0.16 Si; 0,60 ~ 1,20 Mn; ≤0.025 Cr; ≤0.30 Ndi; ≤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.
