Abstract
The impurities sulphur, phosphorus, lead, bismuth, tin and antimony affect the hot workability of stainless steels. In this study we show that lead segregate to phase and solidification-grain boundaries, where cracks appear during hot deformation. The workability was tested by the hot bending of laboratory steels.
