305, 1.4303, SUS305, Stainless Steel Spring Wire
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.
