Heat Treatment of Cold Formed Springs Made from Oil Hardened and Tempered Spring Steel Wire

摘要

The heat treatment after cold forming is used to decrease the residual stresses of springs, but the mechanical characteristics of the spring steel wires alters, too. This presentation describes the influence of the heat treatment technology (oven equipment, temperature, duration,...) to the properties and quality of helical compression springs made from oil hardened and tempered spring steel wire.
