Representative Grades / K Cast Iron Material Work Application Examples Cast Iron Grades High Speed Continuous Cutting General Purpose Mill-Scaled Work/Interrupted Cutting AC405K / AC415K / AC420K A AC405K：Suitable for high-speed continuous cutting with excellent resistance to wear and plastic deformation. AC415K：First recommended grade for cast iron turning provides stability and long tool life in a wide range of processes. Grades AC420K：Superior fracture resistance provides excellent stability in interrupted unstable cutting and when cutting mill-scaled work. ● Improvements to super FF-TiCN coating grain and hardness provide significantly improved wear resistance. Newly developed stress control technology enhances micro-grained α Alumina (FF-Al2O3) coating for superior reliability. Steel ● Coating Coating stress control technology reduces abnormal Stainless Structure damage caused by chipping. Steel Micro-grained Ș Alumina (FF-Al2O3) Improved adhesion and peel-off Chipping Cast Iron Super FF-TiCN Ultra-fine grained, ultra-hard TiCN coating Alloy Exotic increases wear resistance 1.5 times.
