Grade 304 Stainless Steel Wire

Type 304 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 304 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 304 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. Smart Craftsmen soap coated Type 304 stainless steel wire is available in the size range 0.014" to 0.625". All wire conforms to ASTM-A-313 and AMS-5688.
