1095 High Carbon Spring Steel Strip

Spring steel is a type of steel that is specifically used to make springs and elastic parts because it can return to its original shape after bending, compression, or extension. This ability, known as elasticity in the quenched and tempered state, arises due to the high yield strength of the steel, which comes from its specific composition and hardening process. Fabricating spring steel requires advanced technical skills to ensure high quality. Any defects on the surface, such as decarburization or irregularities, can reduce fatigue strength. Baomit strip steel ensures that the springs have a perfectly smooth surface for optimal efficiency and performance.
