Hay Fore supertech offers valves in a variety of materials to fit any engine. * Stainless Steel – Manufactured as a one-piece forged valve for strength and reliability. Supertech primarily uses EV8 (21 – 4 N) for intake and exhaust valves, however there are other alloys used with different heat treatments for valve manufacturing for specific applications. To address the issue of high heat output, supertech uses two different types of coatings, coating: Chrome, widely used in nitride valves, black color – this is a hardening treatment that provides a smooth surface then plated on chrome valves and produces less friction between stem and guide. * Inconel 751 – Nickel Base Alloy – Nickel Base Alloy is used for exhaust valves that reach very high temperatures, such as those in Turbo or Supercharged applications. supertech valves are sold by *valve*.
