摘要：

The influences of rolling temperature and the addition of small amount of various alloying elements on flow stress during cold forging were investigated in JIS SWRCH20A. It was observed that low temperature rolling and additions of B are effective in reducing the flow stress. The flow stress of B-containing steel rolled at low temperature was found to be equivalent to that of conventional spheroidizing annealed SWRCH20A. As a result of these developments, the elimination of softening heat treatment prior to cold forging has become possible.
