Spring Steel

Spring steel is a high-carbon or medium-carbon alloy steel. It is specifically designed to withstand repeated bending, twisting, and heavy loads without permanent deformation. Common grades include 65Mn, 60Si2Mn, and 55CrSi, which offer varying levels of strength and flexibility. Spring steel is widely used in automotive suspensions, industrial machinery, tools, and consumer products like mattresses and clamps. Its key properties include high yield strength, good toughness, and the ability to return to its original shape after stress. Heat treatment processes like quenching and tempering enhance its mechanical properties, making it ideal for high-performance applications.
