GB 60Si2Mn Spring Steel: Properties, Uses & Manufacturing Guide
GB 60Si2Mn spring steel is a silicon-manganese alloy steel defined by the Chinese National Standard GB/T 1222. It is engineered for demanding spring applications that require high elasticity, excellent fatigue resistance, and exceptional strength. Its high silicon content (1.50-2.00%) is the key differentiator, significantly boosting its elastic modulus and ability to return to its original […]
