1074 Spring Steel Wire

↵

1074 Spring Steel Wire is a high-carbon spring steel wire manufactured according to standards such as ASTM and SAE. It is mainly used to manufacture elastic elements that withstand repeated elastic deformation. Typical applications include mechanical springs, fasteners, and spring-loaded structural components.

High Strength

With a carbon content of 0.70–0.80%, it forms a predominantly martensitic microstructure after quenching and tempering, resulting in a tensile strength ranging from 1200–2200 MPa.

High Elastic Deformation

With a yield strength ≥1080 MPa and an elongation of 5–10%, it maintains an elastic deformation range under high stress levels during loading.

High Surface Finish Adaptability

Available for bright, galvanized, phosphated, and oiled surface finishes. The galvanized layer isolates the environment, while the phosphated layer improves lubrication and subsequent forming processes.

Spring manufacturing industry: Used in compression springs, tension springs, and torsion springs to provide restoring force under cyclic loads.

Automotive parts industry: Used in suspension springs, seat springs, and fastening elastic elements to withstand dynamic loads during operation.

Machinery equipment industry: Used in various return mechanisms and buffer devices to store and release energy during mechanical motion.

Hardware products industry: Used in wire forming parts and elastic connectors, providing fixation and springback in assembly structures.
