The effect of lead on the hot workability of austenitic stainless steel with a solidification structure

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.
