Valve Steels

These highly alloyed (Mn-Ni-Cr-Mo-N) magnetic and non-magnetic steels are used for Inlet & Exhaust Valves for IC Engines, which function under conditions of severe heat and corrosion stress. These grades of steel are known to retain their properties at elevated temperatures. Ever Nickel Alloys offers a bouquet of material for these demanding applications.
