  • AISI 302/304 Stainless Steel Wire Springs

    – This is the most popular stainless steel alloy for springs, exhibiting good tensile strength, high corrosion resistance, good heat resistance, and slight magnetic properties. It maintains its strength at temperatures up to 550 degrees F. 302/304 is cold drawn and meets ASTM A 313 standards.

  • AISI 316 Stainless Steel Wire Springs

    – 316 stainless steel wire exhibits better corrosion resistance than 302/304 alloy wire, though it has less tensile strength. It has superior cold forming properties and exhibits short term tensile and creep strength at temperatures up to 550 degrees F. It is used for springs in corrosive environments that do not require high impact or load strength. It meets ASTM A 313 standards.

  • 17-7 PH (AISI 631) Stainless Steel Springs

    – An excellent material for all types of spring applications, 17-7 stainless steel wire offers long life under extreme conditions. It exhibits superior fatigue properties, elasticity, strength-to-weight ration, high yield strength, ductility, and good corrosion resistance, at temperatures up to 650 degrees F.   It meets ASTM A 313 standards.
