We have chosen this material specifically because it’s the highest grade of steel available and provides the strength to withstand just about any application. Our exhaust valves are made from EV16 (21-8N) or EV8-Nb/w for even greater strength at higher temperatures. Our stainless steel valves are one piece forged valves, and depending on the application feature hardened tips, hardened seats, swirl polish, undercut, and our black nitride coating. Our black nitride coated valves feature a harder surface area and a smoother finish, providing less friction and subsequently longer life.
