Menene P235GH? Wane abu ya dace da shi a China?

P235GH babban aiki ne na zafin jiki na Fihekin da bututun ƙarfe na gami, wanda shine ƙarfe mai zafin jiki na Jamusanci. P235GH, EN10216-2 matsa lamba maras karfe bututu yayi dace da kasa misali 20G, 20MnG (GB 5310-2008 high-matsa lamba tukunyar jirgi bututu maras kyau).

P235GH gami karfe bututu maras sumul ne gaba ɗaya narke a cikin wutar lantarki baka makera da oxygen saman-busa Converter. Don manyan buƙatu, yana ɗaukar tacewa a wajen tanderu, injin induction tanderun murɗawa ko murƙushewa biyu, remelting electroslag ko vacuum magani, da magani mai zafi.

P235GH, EN10216-2 matsa lamba ba tare da bututun ƙarfe ba ya dace da masana'antar tasoshin matsin lamba da abubuwan kayan aiki. Idan aka kwatanta da talakawa karfe, P235GH gami karfe yana da mafi girma ƙarfi da taurin, sanyi lankwasawa yi da waldi yi, sinadaran Properties, biocompatibility, jiki Properties da kuma aiwatar yi.

Mechanical Properties na P235GH gami karfe bututu: tensile ƙarfi σb350 ~ 480 MPa; ƙarfin yawan amfanin ƙasa σs≥215 MPa; elongation δ5≥ 25%; tasiri sha makamashi Akv≥47 J; Brinell taurin ≤105 ~ 140 HB100

Abubuwan sinadaran (ƙasassun taro,%) na P235GH gami da bututun ƙarfe: ≤0.16 Si; 0.60 ~ 1.20 Mn; ≤0.025 Cr; ≤0.30 Ni; ≤0.30 Ku; ≤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.
