Black Nitride Valves

INCONEL 751 - NICKEL BASE ALLOYS:
This Nickel base alloy material is used for exhaust valves in engines that reach very high temperatures and its use is growing with the application of turbos and superchargers.
The Inconel valves are made from a Nimonic 751 alloy which has better resistance to heat then stainless steel.
The Inconel valves are only used on the exhaust side, it is the only side that it is needed to use a higher temperature alloy.
