0.1420 in, Type 17 Chrome – 7 Nickel Wire

Type 17 chrome – 7 nickel stainless steel wire (AISI 631) has the corrosion resistance of Type 302 plus superior strength and heat resistance. This grade of stainless wire possesses high elastic qualities similar to music wire while maintaining the corrosion resistant qualities of the standard Type 302 stainless. The alloy is an excellent material for all kinds of springs where long life is required under severe service conditions, providing excellent fatigue properties, ductility, high yield strength, modulus of elasticity, and strength-to-weight ratio.
