ASTM 9255 is a type of C-Mn steel used for spring applications. Silicon and manganese in steel can significantly improve elasticity, strength and flexion ratio, hardenability, tempering stability and relaxation stability. ASTM9255 steel bar can be used as a damper plate spring, coil spring, cylinder relief valve spring, and can be used as a heat resisting spring under 250℃.
