Machining Inconel 800 steel plate is challenging, primarily due to its high high-temperature strength, significant work hardening tendency, and poor thermal conductivity. These characteristics result in high cutting forces, high cutting temperatures, rapid tool wear, and easy chip adhesion, affecting the surface finish.
Its high nickel-chromium content and austenitic structure are the root causes of the machining challenges. Inconel 800 machining requires the use of carbide tools and strict control of cutting parameters, such as reducing cutting speed and increasing feed rate, to cope with the Inconel 800 material's high-temperature strength and work hardening.
To improve machining efficiency, it is recommended to use YG-type carbide tools containing Ta (Nb) and employ coating technologies, such as CA15 and CA25 coatings, to enhance the tool's wear resistance and heat resistance. Furthermore, optimizing cooling and lubrication conditions also helps reduce cutting temperatures and extend tool life.
