AMASTEEL Cast Steel Shot is tempered martinsite steel with the perfect grain structure for endurance and impact value. Produced from select steel scrap, controlled atomization process and a unique quench & temper thermal treatment, AMASTEEL is unparalleled to all producers of metallic abrasives. AMASTEEL is produced with precise control of the microstructure to deliver maximum durability and impact energy transfer. In a peening application, AMASTEEL Cast Steel Shot is used to impart compressive strength to torque or load bearing metal parts, such as jet engine turbine blades, automotive springs, or heavy equipment crankshafts. As a blast cleaning medium, the shot is used to remove various forms of surface contamination from a broad spectrum of steel or foundry products.
