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.

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.
