55SiCr wire is an important silicon-manganese spring steel wire. 55SiCr wire exhibits excellent hardenability, ensuring the spring has significant strength and stiffness in all cross-sections. This characteristic allows the spring to carry heavy loads without breaking, and at the same time has a high elastic modulus, allowing it to quickly return to its original state after being stressed. In addition, 55SiCr wire also has excellent fatigue resistance and can maintain its excellent performance under long-term alternating stress.
