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

Mar 02, 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.

•1115°F to 1300°F (600°C to 700°C) for hot-work and high-speed tool steels. For many alloy steels, little or no stress relief occurs at temperatures less than approximately 500°F (260°C), while approximately 90% of the stress is relieved by 1000°F (540°C).

Stress-relieving is needed after welding

Stress-relieving should always be considered. At elevated temperature the yield strength of materials is reduced, relative to that at room temperature. Since the residual stress cannot exceed the yield stress, plastic flow will reduce the excess to the level of yield strength at that temperature.

Annealing (metallurgy) - Wikipedia

Process annealing. The temperature range for process annealing ranges from 260 °C (500 °F) to 760 °C (1400 °F), depending on the alloy in question. This process is mainly suited for low-carbon steel. The material is heated up to a temperature just below the lower critical temperature of steel.

How to relieve stress in welding - The FABRICATOR

Back to basics on stress relief and reducing distortion. Relieving residual stress through welding technique as well as temperature control can greatly reduce weld distortion. It's a shame arc welding works so well. It's proven, cost-effective. For many applications, nothing comes close, at least not yet.

Heat Treatments Stress 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.

Stress Relieving Heat Treatment for Austenitic Stainless Steel

Stress Relieving Heat Treatment for Austenitic Stainless Steel. Unlike martensitic stainless steel, the austenitic stainless steel are not hardenable by heat treatment as no phase changes occur on heating or cooling. Softening is done by heating in the 1050/ 1120C range, ideally followed by rapid cooling.

Stress-relieving is needed after welding

Most Stress-relieving operations are carried out in air furnaces. In air, alloys are subject to discoloration or scaling depending on the alloy and temperature used. Post-treatment cleaning or scale removal treatments are therefore often required. Time dependent stress relaxation will further reduce most of remaining residual stresses.
