Steel shot is manufactured by melting selected scrap in electric induction furnace. The chemical composition of molten metal is analyzed and strictly controlled by spectrometer to obtain SAE Standard specification. The molten metal is atomized and transformed into round particle and subsequently quenched and tempered in a heat treating process to obtain a product of uniform hardness and microstructure, screened by size according to SAE Standard specification.
