The Characteristics of High Chromium Cast Iron Machining

The chromium content of high chromium cast iron is w(Cr)=11%-28%. Cr can be dissolved in ferrite to form carbides. Since high-chromium cast iron is a high-temperature 

wear-resistant cast iron, the addition of chromium improves wear resistance, and a dense Cr2O3 protective film is formed on the surface of the casting, which can be used 

to manufacture wear-resistant castings working at temperatures higher than 800 °C.

The cutting process of high-chromium cast iron with large cutting force and high cutting temperature. The tool is subjected to large impact force, easy to vibrate, and the chip

is broken. Due to the high chromium content, sticking often occur. Our IBN100 Solid PCBN Inserts with high red -hardness and better wear resistant than ceramic tool materials 

in processing high chromium cast iron materials. High cutting speeds are available for better surface quality.
