P235GH chii? Inoenderana nei kuChina?

P235GH ipombi yesimbi yeFihekin ne alloy inoshanda zvakanyanya pakupisa, inova simbi yekuvaka yeGerman inodziya zvakanyanya. P235GH, EN10216-2 pombi yesimbi isina musono inoenderana neyakajairika yenyika ye20G, 20MnG (GB 5310-2008 pombi yesimbi isina musono yeboiler ine musono).

Pombi yesimbi yeP235GH alloy pombi isina musono inowanzo nyungudutswa muchoto chemagetsi che arc uye oxygen top-blown converter. Kuti zvive zvakakosha, inoshandisa kunatswa kunze kwechoto, kunyungudutswa kwechoto che vacuum induction kana kunyungudutswa kwe vacuum kaviri, kurapwa kwe electroslag remelting kana vacuum, uye kurapwa kwekupisa.

P235GH, EN10216-2 pombi yesimbi isina musono yakakodzera kugadzira midziyo yekumanikidza nemidziyo. Kana ichienzaniswa nesimbi yakajairika, simbi yeP235GH ine simba rakawanda uye kusimba, kugona kukotama nekukwesha, kugona kwemakemikari, kugona kuenderana nezvinhu zvipenyu, kugona kwemuviri uye kugona kwekushanda.

Hunhu hweP235GH alloy steel pombi: simba rekudhonza σb350~480 MPa; simba rekugovanisa σs≥215 MPa; kureba δ5≥ 25%; simba rekunyudza simba Akv≥47 J; kuomarara kweBrinell ≤105~140 HB100

Kuumbwa kwemakemikari (chikamu chikuru, %) yeP235GH alloy steel pombi: ≤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.
