Introduction

What Is Involved in Stress Relieving Steel? (with pictures)

Jan 22, 2019 · Stress relieving steel is a heat treatment process that involves subjecting a steel workpiece or part to a specific temperature for a particular amount of time. The temperature at which stress relieving takes place is determined by the transformation temperature, which can be a different figure for various steel alloys.

Heat TreatmentsStress Relieving eFunda

Stress relieving is done by subjecting the parts to a temperature of about 75 ºC (165 ºF) below the transformation temperature,line A 1 on the diagram, which is about 727 ºC (1340 ºF) of steel—thus stress relieving is done at about 650 ºC (1202 ºF) for about one hour or till the whole part reaches the temperature. This removes more than 90% of the internal stresses.

How to relieve stress in welding The FABRICATOR
