ThermoFusion is the only combined heat treating and brazing company in the Bay Area. We offer an extensive selection of heat (and cold) based services. One of our core service offerings is stress relieving.
Stress relieving is a heat treatment process that involves heating the part to a specific temperature below its annealing temperature and then cooling it. It is used to reduce internal stresses in components generated during manufacturing operations (e.g., cutting (flame or laser), forming, machining, rolling, or straightening). It is often done before final machining. Proactively removing these stresses reduces the risk of distortion, cracking, and other damage occurring in the piece either during final machining, or over time. For this reason, it is often used for parts and products with tight dimensional tolerances, extensive machining requirements, and/or large and complex designs.
Like stress relieving, annealing is used to diminish or eliminate internal stresses in formed, machined, rolled, and similarly processed components. However, the temperatures utilized in stress relieving operations are much lower than those used in annealing operations. Equipped with air, endothermic, and vacuum furnaces, our team can achieve the temperatures needed for both annealing and stress relieving treatment processes (600° F to 1,400° F). While we offer these services for all types of metal and plastic, our most commonly processed materials are aluminum, titanium, steel, and plastic.
There are many factors to consider when deciding whether stress relieving treatments are necessary for a manufactured component. Some of the considerations to keep in mind include:
For steels, it is especially important to keep temperatures below the point at which austenitization occurs. The cooling time needed may also be influenced by the material. Some materials, such as high-carbon steels, are prone to surface cracking if cooling occurs too quickly.
ThermoFusion, Inc. is a leading provider of heat-treating services for components made from various materials and for a wide range of industries and industrial applications. Equipped with over 50 years of industry experience and numerous certifications (including ISO 9001, AS9100AD, and NADCAP), our team has what it takes to offer quick and efficient solutions for metallurgical challenges.
