Stainless Steel Valves:
Supertech intake valves are made exclusively from enhanced versions of EV8 (21-4N) steel. This is the highest grade of steel available and provides the strength to withstand just about any application. Supertech exhaust valves are made from EV16 (21-8N) or EV8-Nb/w for greater strength at higher temperatures. Some applications call for hardening of certain areas such as the tips and or the seats. For these applications, Supertech will often times weld other hard metal alloys to the valve for increased durability.
Black Nitride Coating:
This is a hardening treatment that has been steadily growing in popularity over the last several years. These black Nitride coated valves feature harder surfaces and smoother finishes, providing less friction and subsequently longer life.
