302 stainless steel wires

Type 302 stainless steel wire is a general purpose stainless alloy typically composed of 18% chromium and 8% nickel. It is the most widely used stainless spring wire because of its high corrosion resistance properties and good tensile strength. For spring applications it is generally furnished in the cold drawn condition. Type 302 springs have good strength at moderate temperatures. If properly treated after forming they will set less than most other spring materials at temperatures up to 500ºF. Type 302 material in the spring condition is slightly magnetic due to the transformation of some martinsite in the drawing operation. The greater the amount of cold reduction the higher the degree of magnetism. Gibbs soap coated Type 302
