Cast Iron

Grades AC405K / AC415K / AC420K

AC405K: Suitable for high-speed continuous cutting. 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.

AC420K: Superior fracture resistance provides excellent stability in interrupted unstable cutting and

when cutting mill-scaled work. l 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.
