ABSTRACT:
In austenitic free-cutting stainless steel containing lead, decrease of hot workability caused by the addition of lead can be dissolved by adding a specific amount of boron. Thus, there is obtained an austenitic free-cutting stainless steel with improved machinability, corrosion resistance and hot workability of which are maintained at the level of conventional austenitic stainless steel.
