Subaru impreza Motorsport Inconel Exhaust Valve set
8 valves in the set
This is a hardening treatment that even though it is not widely used as the chrome coating, it has several benefits and is becoming very popular, mainly for European and Japanese applications.
The micro-hardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitrated layer (micro-hardness is 800HV minimum). Surface finish is smoother than with chromed stems, having less friction between stem and guide.
Valve seat surface is harder with the nitrated layer, lasting longer with lead free fuels, alcohols, nitro or other “explosive” mixes. Matches any kind of seats (nodular iron seats, steel powder metal seats, hard aluminum-copper seats or beryllium copper seats).
