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.

Spring steel wire is a versatile material that is utilized in the manufacture of a wide array of products. including automotive suspension springs, valve springs, and torsion springs. Beyond springs, paper clips and mattress supports. In addition, spring steel wire is essential in the creation of retaining rings and circlips that are utilized to secure components on shafts or within bores, and in making various types of fasteners. The durability and resilience of spring steel wire also make it a key material in the manufacturing of certain types of cable, fencing, and even some musical instruments, such as piano and guitar strings, where its ability to return to its original shape after deformation is highly valued.
