Heat treatment process for stainless steel wire rod

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 DEG C. and 1050 DEG C. The rod is then held at a temperature between FRT -50 DEG C. and FRT +100 DEG 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 DEG -1050 DEG C., followed immediately by water cooling.
