Abstract In order to avoid and reduce surface cracks of SS400 B-bearing steel slab， the high temperature mechanical properties of SS400 B-bearing steel slab have been investigated in the temperature range of 650-1 350 ℃ by the hot tensile test technique with Gleeble-1500 system. The results showed that its yield strength and tensile strength in the temperature range were relatively small；in general，which decreased with increased tested temperature. Only in the range of 1000-1 100 ℃，SS400 B-bearing steel slab has good hot ductility and the reductions of area were higher than 90%. The third brittle zone of the SS400 B-bearing steel is between 700-950 ℃. The low plasticity temperature range is relatively wide，because of boron segregation in grain boundaries and precipitation of BN leading to the grain boundary embrittlement. Because of the remelting phenomenon of B-bearing steel，the plasticity can be reduced when the temperature lies between 1 150-1 250 ℃.
