High Tensile Chrome Silicon Springs
ASTM - A401 is best suited for applications that must withstand shock loads, high stress, and temperature environments. It has a high tensile strength and resilience to higher temperature.
This high tensile alloy is cold drawn and heat treated, which makes it stronger and maintains the consistent performance for a longtime even under repeated spring loads.
