P235GH yog cov khoom siv dab tsi? Nws sib raug rau cov khoom siv dab tsi hauv Suav teb?

P235GH yog cov yeeb nkab hlau Fihekin thiab alloy uas ua haujlwm tau zoo thaum kub thiab txias, uas yog cov hlau German uas ua haujlwm tau zoo thaum kub thiab txias. P235GH, EN10216-2 cov yeeb nkab hlau tsis sib haum raws li tus qauv hauv tebchaws 20G, 20MnG (GB 5310-2008 cov yeeb nkab hlau tsis sib haum siab).

P235GH cov yeeb nkab hlau tsis sib xws feem ntau yog smelted hauv hluav taws xob arc cub tawg thiab cov pa oxygen top-blown converter. Rau cov kev xav tau siab, nws siv kev ua kom zoo sab nraum lub cub tawg, lub tshuab nqus tsev induction cub tawg smelting lossis ob chav nqus tsev smelting, electroslag remelting lossis lub tshuab nqus tsev kho mob, thiab kev kho cua sov.

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

Cov khoom siv kho tshuab ntawm P235GH hlau yeeb nkab: lub zog tensile σb350 ~ 480 MPa; lub zog tawm los σs≥215 MPa; elongation δ5≥ 25%; lub zog nqus dej Akv≥47 J; Brinell hardness ≤105 ~ 140 HB100

Cov tshuaj lom neeg muaj pes tsawg leeg (feem pua ​​ntawm pawg,%) ntawm P235GH hlau yeeb nkab: ≤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.
