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.Sullivan Precision Plate Stress RelievingStress relieving,or stress-relief anneal,is done to low carbon grades,in order to remove stresses that have built up in the part from flame-cutting or from mechanical flattening.This is important when the parts will go on to be ground,machined,or fabricated.

What is Stress Relieving? - Definition from Corrosionpedia

Jan 21,2014·A stress relief operation is typically used to remove internal (residual) stresses that have accumulated in the material.These stresses can cause loss of tolerance,cracking and distortion,and contribute to in-service failures.For these reasons,stress relievingtotalmateriaStress Relief of Steels : Total Materia ArticleCarbon steels may be stress relieved by holding a temperature at 1100 to 1250°F (600 to 675°C) for 1 hour per inch (25 mm) of thickness.Stress relieving offers several benefits.For example,when a component with high residual stresses is machined,the material tends to move during the metal removal operation as the stresses are redistributed.After stress relieving,however,greater dimensional stability is maintained during machining,providing for increased dimensional reliability.Wallwork Stress Relieving Normalising of SteelsCarbon steels and alloy steels can be given two forms of stress relief:Treatment at typically 150-200°C relieves peak stresses after hardening withoutTreatment at typically 600-680°C (e.g.after welding,machining etc.) providesWhat Is Involved in Stress Relieving Steel?
