Hot Rolled, Cold Drawn Carbon Spring Steel/Alloy Spring Steel


Spring steel mainly has good elasticity, and because it works under a dynamic load environment, the most important material for manufacturing spring should have high yield strength; Spring is used under the impact, vibration, or long-term cross stress, so spring steel is required to have high tensile strength, high elastic limit, and high fatigue strength. In terms of process, spring steel is required to have certain hardenability, not easy to decarburize, and good surface quality, that is, high-quality carbon structural steel with carbon content WC in the range of 0.6% – 0.9%. In recent years, combined with Chinese resources and according to the requirements of new technologies for automobile and tractor design, a new steel type with boron, niobium, molybdenum, and other elements added to silicon manganese steel has been developed, which has prolonged the service life of the spring and improved the quality of the spring.

Main uses :

The application of spring steel has high precision, good toughness, good wear resistance, and stable quality. Spring steel is widely used to make all kinds of springs, such as leaf springs, Coil Springs, Cylinder Safety Valve Springs, and some important springs which work under high stress It can also make valve springs, Spring Ring, shock absorbers, clutch springs and brake spring.
