An Analysis on Surface Cracks Formation of H Beam of Nb-V Microalloying Steel BS55C
The causes of surface cracks formation of H beam of Nb-V microalloying steel BS55C-0. 14~0. 17C,0.45~0.55Si,1.25~1.45Mn,0.08～0. 10V,0.03～0.05Nb have been analyzed. The results showed that the steel was sensitive to longitudinal crack at solidification and its plasticity at 700~950 ℃ was lower,there...
