STELLITE® 20 is the most abrasion resistant standard cobalt base alloy. It also has good corrosion resistance. Whilst it has low shock resistance, it is often the only answer for some applications such as slurry pumps or chemical resistant parts. Examples include pump sleeves, rotary seal rings, wear pads, bearing sleeves and centerless grinder work rests. Very similar to STELLITE® Star J. |
