About
The use of stainless spring steels has increased considerably in recent years. Several new compositions are now available to withstand corrosion. All of these materials can be used for high temperatures up to 650°f.
Springs are specifically designed to be resilient, even when going through vigorous deflections. A key component to this resiliency is in the spring material. The choice of material is based on numerous factors ranging from fatigue strength, cost and availability, corrosion resistance, magnetic permeability and even electrical conductivity. See the pages below for important information on spring material properties and do not hesitate to contact us with any questions!
The corrosion resistance of stainless steels removes the requirement for any additional protective coatings making them the ideal material for springs operating in a range of corrosive conditions, high temperatures and in locations where maintenance and replacement are difficult.
offering consistent spring forming capabilities.
to lubricate and aid the forming of the springs when running at high speeds through spring forming machines providing good spring coiling characteristics.
offering maximum product performance.
