Steel Ball Measuring Diameter
  • These stainless steel balls are made from AISI 316 Stainless Steel.
  • Un-hardened but consistently hard all the way through the ball to achieve maximum strength and quality.
  • Ball hardness is controlled within the 25 - 39 HRC range as measured on parallel flat surfaces.
  • Ball grades are defined numerically 50 - 1000 (50 being highest quality available in 316 stainless, 1000 is the lowest)
  • 316 Stainless balls are NOT attracted to magnet but may show response to magnets after cold working.
