Stress-relieving is the process generally specified after welding of most materials.Removing or reducing the residual stresses generated by welding is required for improving the dimensional stability of weldments.In certain applications,internal residual stresses can sum up with those generated by externally applied loads.Stress relieving on metal products - Heat treatment Stress relieving.Stress relieving is carried out on metal products in order to minimise residual stresses in the structure thereby reducing the risk of dimensional changes during further manufacturing or final use of the component.Benefits.Machining,and cutting,as well as plastic deformation,will cause a build up of stresses in a material.Stress relieving mild steel weldmentsFeb 11,2016Stress relieving welded steel frames Stress relieving mild steel weldments#0183;Thin material (less than 1/8 in thick) typically does not require stress relief because cracking is less of a concern.Thicker materials are commonly stress-relieved at 1,050 deg F to 1,250 deg F for approximately one hour per inch of base material thickness.

For mild steel it is customary to prescribe stress relieve at 650 0 C for one hour per every 25 mm (one inch) of thickness.Hardenable carbon steels are often regulated by Codes that prescribe under which conditions this treatment is required.
