Heat Treating Springs

Heat treatment refers to a process used to prepare materials for precision spring fabrication. This process relieves stress from the metal, which allows it to hold its shape once the spring is formed. The temperature to which the metal must be heated – and the duration for which it must be held at that temperature – varies depending on the material being used. The material is then cooled using a highly controlled process and cooling rate, to ensure that no new residual stress occurs.

When you need to get the most from metal springs, consider putting them in the furnace at Custom Spring Manufacturing. Our precision heat treating processes can alter their properties to achieve amazing performance advantages.

How Does Heat Treating Work? 

Heat treatment is a process in which metal is heated without reaching a molten stage before being cooled under tight controls to obtain desired properties. It can be utilized to achieve many results.

The process can soften metal to improve formability or harden it to boost strength. It can impart a hard surface on relatively soft components, increasing abrasion resistance. Parts that may otherwise corrode can be given a corrosion-resistant exterior. Brittle products can also be toughened.

Leading Heat Treatment Services 

Custom Spring Manufacturing is happy to provide heat treatment as a value-added service for our clients. A leading spring manufacturer, we leverage the process to relieve stress from metal, allowing it to hold a shape once the spring is formed.

The temperature to which the metal must be heated, and the duration for which it must be held at that temperature, varies depending on the material being used. We can heat treat just about any material, but examples include:
