Stress Relief Furnaces

Stress Relief Furnaces relieve stresses in materials generated by welding, machining, or heat processing.

The purpose of a Stress Relief Furnace is to raise the temperature of a component to slightly below the transformation temperature. This elevation in temperature eliminates internal stresses caused by secondary processes such as welding, machining, or cold forming. Upon reaching completion of the heat-up and hold cycle, the parts are then cooled at a controlled rate.

There are many advantages to stress relieving:
It relieves internal stresses without causing any color change.
It returns the material to a strength level approximately equivalent to where it was prior to forming.
It increases mechanical strength of the material.
Welded structures can be made tension free by stress relieving.

Overview

Stress Relief Furnaces relieve stresses in materials generated by welding, machining, or heat processing.

The purpose of a Stress Relief Furnace is to raise the temperature of a component to slightly below the transformation temperature.

Each Industrial Furnace project undergoes a comprehensive evaluation of every production requirement. The assessment includes areas such as production goals, part configuration and construction, part mass, temperature profile, and facility location or elevation.
