Learn about Nitronic® 60, a premium Stainless Steel alloy commonly used in bearings, shafts, valves and more.
Nitronic® 60 Overview
Nitronic 60, also referred to as Alloy 218, is a stainless steel designed for excellent wear resistance and anti-galling performance. Its enhanced properties are primarily due to the addition of silicon and manganese, which help minimize wear and prevent galling under friction-intensive conditions.
