ASTM 1572 Round Steel Bar

AISI 1572 is a type of high manganese spring steel, is characterized by high elastic limit, yield strength and fatigue strength, with large hardenability and small decarbonization tendency. It has good machinability and relative machinability of 70% in the annealing state, but it is sensitive to overheating, easy to produce quenching cracks and temper brittleness. AISI/ASTM 1566 is used for making large flat spring, cushion spring and spring, and it is also suitable for making spring ring, valve spring, clutch spring, brake spring cold drawn wire (≤7mm), cold coil spring, etc. It is also the main material for making a diamond circular saw blade.
