Benefits of Spring Steel


Spring steel is usually used because of its high yield strength, resistance to deformation, and ability to restore its original shape.


Precision Steel also has a large stock of stainless steel spring strip steel. Stainless steel spring steel is famous for its waterproof, environmental resistance and pollution resistance. There are two major categories, stainless steel spring steel can be austenitic or martensite. Austenitic stainless steel spring steel strips such as 301 and 302 are tempered and rolled into light springs, while martensitic spring steels (such as 420 stainless steel strips) can be heat treated to obtain high hardness and toughness, and are usually used for quenching tools.


At Precision Steel, our sales representatives are experts in spring steel products. Let us help you find the right spring steel for your application.


It is impractical to formulate flatness tolerances of cold-rolled carbon spring steel to express the range of width and thickness, as well as the various characteristics produced in coils and cut lengths.

Our high-performance spring steel is used in applications that require components that can reliably absorb and reapply forces. A good example of this type of application is a spring diaphragm in a car or a retractor spring in a seat belt system, both of which have been tempered and re-rolled.

The elasticity of the spring steel plays an important role in the functionality of these dynamically highly loaded parts. It determines how much force the material is able to absorb without being permanently deformed. The yield strength represents the maximum force which the material can absorb and subsequently release while still returning to its original shape.

Yield strength is an important parameter which we are capable of calibrating to a precise degree thanks to our experience combining chemical composition, cold rolling and heat treatment. When it comes to spring steels, we are able to manufacture various high-performance materials with yield strengths (Rp0.2) of up to 2,800 MPa (406 ksi).

Our products withstand countless millions of loading and unloading cycles over the course of their service lives. In several cases, such as those described above, these parts perform safety-related functions. Get in touch with us to discuss exactly what you need. We will manufacture a custmized spring steel to perfectly meet your project requirements.
Spring steel is a name given to a wide range of steels used in the manufacture of springs, prominently in automotive and industrial suspension applications. These steels are generally low-alloy manganese, medium-carbon steel or high-carbon steel with a very high yield strength. This allows objects made of spring steel to return to their original shape despite significant deflection or twisting.
Spring steel is often used because of its high yield strengths, resistance to deformation, and its ability to return to its original shape. Our spring steel and spring steel strips are available as heat-treatable annealed, which allows the forming to occur prior to the heat treatment, or heat treated, where the steel is previously hardened, tempered, or sprung. Our inventory of annealed spring steel can be easily formed, tempered, heat treated, blanked or shaped.
