Tsis muaj cua sov yog nqa tawm hauv cov txheej txheem tsim khoom, yog li tsis muaj qhov tsis xws li pitting thiab nplai uas feem ntau tshwm sim hauv kub dov, thiab qhov zoo ntawm qhov chaw yog qhov zoo thiab qhov smoothness siab.
Qib | Yield zog ReL / （MPa） | Tensile zog Rm / (MPa) | Elongationb A50 (%) (L0=50mm,b=25mm) |
CR550/980 QP | 550-750 | Ntau dua lossis sib npaug li 980 | Ntau dua lossis sib npaug li 18 |
Nco tseg: a. Noj Rp0.2 nyob rau hauv cov ntaub ntawv ntawm indistinct tawm los, txwv tsis pub ReL b. Siv P7 qauv los ntawm kev siv GB / T 228.1, perpendicular mus rau cov kev taw qhia ntawm dov. | |||
Cov qauv siv nyob rau hauv ntau lub teb chaws los tsim cov kev cai rau cov hlau txias, xws li EN 10130, EN 10268, EN 10209, ASTM A1008 / A1008M, DSTU 2834, GOST 16523, GOST 9045, GOST 17066 thiab lwm yam Qhov loj me me rau cov coils txias, lawv daim ntawv thov (profiling, txias sib sau, enamelling, siv dav, thiab lwm yam), txhua yam khoom, nto zoo thiab lwm yam tsis.
