Supertech valves are made in various materials including Stainless Steel alloys, Nimonic, Inconel, Stellite Titanium, etc. There are different alloys, heat treatments and coatings used for different applications and they are continuously researching and testing new materials and applications.

For intake valves Supertech primarily uses enhanced versions for EV8 (21-4n) and for exhaust valves they mostly use EV16 (21-8N) or EV8-Nb/w for greater strength at higher temperatures. Some applications call for Supertech to harden certain areas such as the tips and or the seats, because of this they often times weld other hard metal alloys for increase durability.

Black Nitride Coating is a hardening treatment that even though it is not as widely used as the chrome plating, it has several benefits and has become more popular for use in the European and Japanese applications.

Benefits of Black Nitride Coating:

- The micro hardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitrided layer (micro hardness is 800HV minimum)

- Surface finish is smoother than with chromed stems, having less friction between the 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).

- Higher rpm engines take full advantage of all the previous features. The higher the engine speed the bigger the power loss due to internal engine friction! The black nitride layer reduces this power loss due to less valve-guide friction.

- The nitrided layer is adhered to the base material at a microscopic level, so it will not "flake" or bake when the valves bend due to impacts with the pistons

- The Black Nitride applies to the whole valve while the chrome coating is only applied to the stem.

- All valves are swirl polished, have stem undercut, a hardened tip and more.

Inconel valves are used for exhaust valves in engines that reach very high temperatures and its use it growing with the application of turbos and superchargers.
