Weight per coil: 50 to 600kg Some material grades of stainless steel wire brief intoduction: 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 stainless steel wire is available in the size range 0.014" to 0.625". All wire conforms to ASTM-A-313 and AMS-5688. Similar in composition to Type 302, Type 316 stainless steel wire has a slightly higher nickel content and 2-2.50% molybdenum giving this alloy better corrosion resistance. Type 316's tensile strength is 10-15% lower than that of Type 302, and the alloy is slightly less magnetic in the spring temper than Type 302. With its superior cold working properties, it can be used for severe cold forming operations and exhibits short time tensile and creep strength properties at elevated temperatures. Gibbs Type 316 stainless steel wire is coated for coiling and is available in the range 0.015" - 0.625" conforming to ASTM A 313. Nickel coated available on application in size range 0.007" to 0.130"
