The normal top size of media used is 10-25mm, but even smaller grinding balls can be used for very fine grinding. Isa Mills: <0.1" grinding balls are recommended. The Isa Mill is more efficient when using small media (i.e. high-chrome steel balls). Rotary Mills: Small cylpebs (<1") are effective in ultra-fine wet regrinding operations.
According to different chromium contents, the cast steel ball can be classified into: High-chromium steel ball: chromium content ≥10%, HRC≥58%, ak≥3J/cm2 Medium-chromium steel ball: chromium content:3%-7%, HRC≥47%, ak≥2J/cm2 Low-chromium steel ball: chromium content: 0.5%-2.5%, HRC≥45%, ak≥1.5J/cm2

Chrome plating is a technique of electroplating a thin layer of chromium onto a metal object. Another name for this form of plating is chromium plating. The product of chrome plating is chrome. It appears …
Most ball bearings are made of a type of steel known as high carbon chromium steel, often called chrome steel. This is used for reasons of cost and durability. Bearings are also made from other materials such as stainless steel, ceramics and plastic. Chrome steel will corrode if exposed to moisture so, where corrosion resistance is needed ...
These researchers have concluded that the metal spheres were made of both chromium and steel, an odd discovery due to the fact that the earliest known production of steel occurred around 2000 BC. If …

52100 steel is a high carbon chromium alloy steel that has a density of 7.81 g/cm 3 (0.282 lb/in 3 ). It can be hardened via cold and hot working processes and responds to annealing and tempering and can be strengthened using the heat treatment process. It is readily forged and formed, as well as machined, from its annealed condition.

I think chrome steel refers to high chromium steel like 52100, not chrome plating. If you talk to them you can specify specific alloys. 52100, 440C There are different grades, you can get the good nice and round bearing types, you can also get lower grade -not perfect roundness or size - balls cheaper.
