Standard Diameter: 1-1/4″ / 1.25 Inches Metric Diameter: 31.75mm Grade: 100 Material: 440 Stainless Steel Ball Weight (each): 4.6127 Ounces / 130.767 Grams 440 stainless steel balls offer the precise geometry and fine surface finish that makes them especially useful for bicycles, casters, drawer slides, door locks and many other applications with the added benefit of corrosion resistance. 440 stainless steel is a high carbon martensitic stainless steel which has high strength, good hardness and wear resistance. This type of stainless is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys. Unlike some stainless steel, this 400 series metal has a composition which allows it to be attracted to a magnet.
