Stainless Steel Wire

ASTM A313 Type 347 UNS S34700 Stainless Steel Spring Wire Type 347 is a stabilized austenitic stainless steel similar to type 304 with an addition of Columbium and Tantalum. The columbium serves to produce a stabilized type of stainless steel which is immune to chromium carbide precipitation. Chemical composition C Si Mn Ni P S Cr Other max 0.08 max 1 max 2 9.00-13.0 max 0.045 max 0.030 17.0 - 19.0 (Cb+Ta)10xC min Specification ASTM A313M-2003 Stainless Spring Steel Wires

ASTM A313 Type 321 UNS S32100 Stainless Steel Spring Wire Type 321 is a titanium stabilized chromium nickel austenitic stainless steel. Type 321 has excellent intergranular corrosion resistance after exposure to this temperature range. It also possesses good low temperature toughness and is non-magnetic in the annealed condition. Chemical composition C Si Mn Ni P S Cr Ti max 0.08 max 1 max 2 9.00-12.0 max 0.045 max 0.030 17.0 - 19.0 5xCmin Specification ASTM A313M-2003

ASTM A313 Type 305 UNS S30500 Stainless Steel Spring Wire Type 305 is an austenitic, Chromium-Nickel stainless steel alloy with an increased Nickel content that allows it to be spun and deep drawn easily while decreasing work hardening. This low rate of work hardening makes it suitable for many deep drawing applications. Chemical composition C Si Mn Ni P S Cr max 0.12 max 1 max 2 10.5-13.0 max 0.045 max 0.030 17.0 - 19.0 Specification ASTM A313M-2003 Stainless Spring Steel
