Stainless Steel Balls | SKF
A typical material for ball manufacture contains a composition of 18% chromium and 8% nickel, commonly – known as 18-8 or 302 stainless steel. Type 316 and 316L stainless steel balls have 2-3% Molybdenum, 10-14% Nickel and 18% Chromium. The alloy addition of molybdenum prevents specific forms of corrosion. Type 316L—extra low carbon grade ...

Nickel Chrome Alloys
An example of a Ni/Cr alloy for this type of application is an alloy containing 8%–12% Cr, 1%–4% Fe, 3%–4% Si, 0.3%–1.0% C, 1.5%–2.5% B, and the remaining portion Ni. The hardness of a coating of this material deposited by inert gas shielded arc methods would fall in the range of 40 to 50 Rockwell C.

Consumption of steel grinding media in mills – A review
The austenitic stainless steels are typically only used in acid media requiring non-magnetic balls, owing to their high cost. The Ni–Cr cast irons or nickel-hards are white cast irons alloyed with Ni and Cr. Two groups are used in grinding media, namely medium alloyed nickel hards (Ni-hard 1 and 2) and high alloyed nickel hards (Ni-hard 4).
