Precision components such as industrial bearing races andautomotive gears often distort unpredictably during heat treatmentdue to the deleterious effects of free or unconstrained oilquenching. Press quenching is a method that can be utilized tominimize the distortion of these complex components during heattreatment. This is accomplished in a quenching machine by utilizingspecialized tooling for generating concentrated forces to constrainthe movement of the component during oil quenching. When performedcorrectly, this method of quenching can often achieve therelatively stringent geometrical requirements stipulated byindustrial manufacturing specifications. It can be performed on awide variety of steel alloys. These include high carbonthrough-hardening grades such as AISI 52100 and A2 tool steel, aswell as low carbon carburizing grades such as AISI 3310, 8620, and9310. The relevant aspects of this specialized quenching techniquewill be presented together with a case study of the effects ofprior thermal history on the distortion that is generated duringpress quenching.
