For over 50 years, M & S Spring Company has manufactured torsion springs, compression springs, and extension springs using chrome silicon wire because of its high tensile strength and resilience. Chrome silicon wire springs can withstand high load stresses and temperatures compared to other materials. M & S Spring Company’s chrome silicon springs meet ASTM A401 standards. Chrome silicon is cold drawn and heat treated by the steel mills being used for fabrication.
