摘要： A process for heat treatment of austenitic and ferritic stainless steel wire rod, comprising rolling a stainless steel wire rod with a finishing-rolling temperature (FRT) between 850.degree. C. and 1050.degree. C. The rod is then held at a temperature between FRT -50.degree. C. and FRT +100.degree. C. for 15 to 30 minutes, and is then wire cooled. For the manufacture of austenitic stainless steel wires for the manufacture of springs, the finishing rolling temperature is 1000.degree.-1050.degree. C., followed immediately by water cooling.
