For over 25 years, Atlas metal has manufactured torsion springs, compression springs, and extension springs using bending stainless steel wire because of its mechanical properties and corrosion resistance. We manufacture springs using several stainless steel grades including 302, 304, 316, and 17-7 PH. 304 stainless steel is an extremely popular grade for our springs because of its good tensile strength, good heat resistance, and high corrosion resistance. Our 304 stainless steel springs are cold drawn and meet ASTM A 313 standards.
