Metal Stress Relieving - Heat Treating Services

Metal Stress Relieving - Heat Treating Services 
Heat Treating, Thermal Stress Relieving & Annealing Services

At Accurate Metal Products (AMP), we provide metalworking solutions to industrial customers. In addition to metal fabrication capabilities (e.g., oxy-fuel flame cutting, plasma cutting, and laser cutting), we maintain the ability to perform a range of material treatment and finishing operations so we can deliver components that fully meet the needs of our customers.

One of our heat treating service offerings is thermal stress relieving for carbon steel, and other steel alloys. The treatment is used to alleviate or eliminate internal stresses within a metal component or assembly resulting from previous manufacturing operations (e.g., cutting, forming, machining, welding, etc.). These stresses can cause distortion, fracturing, and other damage to a component if they are not properly handled.

Overview of the Stress Relieving Process

While stress relieving operations can vary slightly from project to project depending on a number of factors (e.g., material, internal stresses, and previous processing operations), they generally involve first heating and then slowly cooling the component.

  • Heating. The component must be heated to a temperature high enough to lower the yield strength to the point where the internal stresses can relieve themselves. The amount of time the component is heated is a minimum of one hour or until the whole piece has reached the desired temperature.
  • Cooling. After the component is fully heated, it is removed from the furnace and cooled in still air. The cooling process must be conducted at a rate slow enough to avoid the formation or introduction of thermal stresses.

Stress relieving can be performed for a variety of materials, ranging from metal to plastic and ferrous to non-ferrous. Steel stress relieving operations typically involve heating temperatures between 800 to 1,300° F.

Benefits of Stress Relieving

Stress relieving is highly beneficial for manufacturing projects. For example:

  • It reduces the risk of material cracking or deforming in future heat treatment operations.
  • It makes metals easier to machine after heat treatment operations.
  • It improves component performance in the intended application.
  • It enhances component resistance to volatile environments.
