After manufacturing the Spools, they are then sent off for a Nitriding treatment.

What is Nitriding? A heat treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. These processes are most commonly used on low-carbon, low-alloy steels. They are also used on medium and high-carbon steels, titanium, aluminium and molybdenum.
