IC806

PVD Coated Grade for Turning and Grooving High Temperature Alloys

ISCAR grade IC806 is a complementary SUMOTEC PVD coated grade for machining high temperature alloys, especially Inconel 718, a nickel based superalloy used extensively in the aerospace industry.

IC806 has a hard submicron substrate with PVD TiAlN coating and a special post coating treatment which provides substantially improved tool life and better reliability. IC806 is recommended for turning Inconel 718 at moderate to high cutting speeds, with stable to mildly unstable conditions.
