Overview
Also called "Nitronic 50", this alloy has exceptional wear, galling resistance, and corrosion resistance superior to 316 stainless. Designed as an all-purpose steel, it is a fully austenitic alloy that maintains its physical properties at elevated and sub-zero temperatures. Additionally, N50 has about twice the yield strength of 304 and 316 stainless. It is typically used in fasteners, pins and bushings, wear rails, roller bearings, pump components, and other marine environments.
NITRONIC is a trademark of AK Steel.
