These stainless steel balls are made from AISI 440 Stainless Steel.
Uniformly hardened and tempered all the way through the ball to achieve maximum strength and quality
Ball hardness is controlled within the 57 - 60 HRC range as measured on parallel flat surfaces.
Ball grades are defined numerically 10 - 100 (10 being highest quality available in 440 stainless, 100 is the lowest)
