Dab tsi yog cov khoom siv P235GH? Cov khoom siv dab tsi nws sib haum rau hauv Suav teb?

P235GH yog qhov ua tau zoo ntawm qhov kub thiab txias Fihekin thiab alloy steel yeeb nkab, uas yog German high-temperature structural steel. P235GH, EN10216-2 siab seamless steel yeeb nkab sib haum rau lub teb chaws tus qauv 20G, 20MnG (GB 5310-2008 high-pressure boiler seamless steel yeeb nkab).

P235GH alloy steel yeeb nkab seamless yeeb nkab yog feem ntau smelted nyob rau hauv hluav taws xob arc rauv thiab oxygen saum-blown converter. Rau cov kev xav tau siab, nws txais kev ua kom zoo sab nraum lub qhov cub, lub tshuab nqus tsev induction rauv smelting lossis ob chav nqus smelting, electroslag remelting lossis nqus tsev kho mob, thiab kev kho cua sov.

P235GH, EN10216-2 siab seamless steel yeeb nkab yog tsim rau kev tsim cov hlab ntsha siab thiab cov khoom siv. Piv nrog rau cov hlau zoo tib yam, P235GH alloy steel muaj zog dua thiab toughness, txias dabtsi yog khoov kev ua tau zoo thiab vuam kev ua tau zoo, tshuaj muaj zog, biocompatibility, lub cev thiab cov txheej txheem kev ua tau zoo.

Cov khoom siv ntawm P235GH alloy steel yeeb nkab: tensile lub zog σb350 ~ 480 MPa; yield zog σs≥215 MPa; elongation δ5 ≥ 25%; cuam ​​tshuam nqus zog Akv≥47 J; Brinell hardness ≤105 ~ 140 HB100

Cov tshuaj lom neeg muaj pes tsawg leeg (feem ntau, %) ntawm P235GH alloy steel yeeb nkab: ≤0.16 Si; 0.60 ~ 1.20 Mn; ≤0.025 Cr; ≤0.30 Ni; ≤0.30 Cu; ≤0.08 Mo; ≤0.02V; ≤0.02 Nb; ≤0.012 N; P; ≤0.010 S; ≤0.30, ≤0.020 Al; C; ≤0.35, ≤0.03 Ti.
