P235GHGH yog dab tsi?
P235GH yog qhov kev ua tau zoo ntawm FECHKin thiab Alloy Steel Yeeb Nkab, uas yog German cov hlau hluav taws kub-kub. P235GH, en {{4 4} hill siab seamless steel yeeb nkab sib haum rau lub teb chaws tus qauv sib raug zoo mus rau tus qauv hauv tebchaws 20g, 20mng (gb {siab boiler seamless steel yeeb nkab).
P235GH Alloy Steel Yeeb Nkab Seamless Yeeb Nkab yog feem ntau smelted los ntawm hluav taws xob arc thiab oxygen sab saum toj-tshuab converter. Rau cov kev xav tau siab, nws ua kom sov kom huv si, siv lub tshuab nqus tsev sib xyaw lossis kev kho nqus dej, kev kho cua sov.
P235GH, en {10216-2 cua siab seamless steel yeeb nkab tau tsim tsim cov hlab thiab cov cuab yeej siv. Piv nrog dog dig hlau, P235GH Alloy Alloy Steel muaj lub zog siab dua thiab kev ua haujlwm sib tsoo, tshuaj lom neeg, cov khoom siv rau lub cev thiab cov txheej txheem kev ua haujlwm.
