Chii chinonzi P235GH? Inoenderana nei zvinhu muChina?

P235GH ndeyepamusoro-tembiricha inoitwa Fihekin uye alloy simbi pombi, inova yeGerman yakakwirira-yekushisa simbi yekugadzira. P235GH, EN10216-2 kudzvinyirirwa isina musono simbi pombi inoenderana nenyika mureza 20G, 20MnG (GB 5310-2008 high-pressure boiler seamless simbi pombi).

P235GH alloy simbi pombi isina musono pombi inowanzonyungudutswa muchoto chemagetsi arc uye okisijeni yepamusoro-inofuridza inoshandura. Pamusoro pezvinodiwa zvakanyanya, inotora kunatsa kunze kwechoto, kunyungudutsa kwevira induction furnace kana kunyungudutsa vacuum kaviri, electroslag remelting kana vacuum kurapwa, uye kupisa kupisa.

P235GH, EN10216-2 kumanikidza seamless simbi pombi yakakodzera kugadzira midziyo yekumanikidza uye zvigadzirwa zvemidziyo. Kuenzaniswa nesimbi yakajairwa, P235GH alloy simbi ine simba repamusoro uye kuoma, kutonhora kwekukotama kuita uye kuita kwewelding, zvimiro zvemakemikari, biocompatibility, zvimiro zvemuviri uye maitiro ekuita.

Mechanical properties yeP235GH alloy steel pipe: tensile simba σb350 ~ 480 MPa; goho simba σs≥215 MPa; kureba δ5≥ 25%; simba rekutora simba Akv≥47 J; Brinell kuoma ≤105~140 HB100

Kuumbwa kwemakemikari (chikamu chemazana, %) yeP235GH alloy steel pipe: ≤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.
