This is 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 greater strength at higher temperatures. Some applications call for us to harden certain areas such as the tips and or the seats. For these applications we will often times weld other hard metal alloys to the valve for increased durability.\u003c\/p\u003e\n\u003cdiv class=\"icon\"\u003e\u003cimg class=\"photo\" height=\"83\" width=\"88\" alt=\"\" src=\"https:\/\/www.supertechperformance.com\/var\/images\/missing\/0000-88x83s.jpg\"\u003e\u003c\/div\u003e\n\u003ch3\u003eBlack Nitride Coating\u003c\/h3\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThis is a hardening treatment that has been steadily growing in popularity over the last several years.
