High-speed tools are divided into molybdenum high-speed steels and tungsten high-speed steels. Molybdenum high speed tool steels are known as Group M steels. They have lower initial cost even though both types of high-speed steels are equivalent in performance. Tools made using high-speed tool steels can be coated with titanium carbide, titanium nitride, and other coatings by physical vapor deposition process for enhancing performance and prolonging life of the tool. There are different types of molybdenum high speed tool steels. Except M6, M 1 to M 10 contains some tungsten, but no cobalt. M36 is a type of molybdenum high speed tool steels.
The following table shows chemical composition of M36 molybdenum high speed tool steels.
The physical properties of M36 molybdenum high speed tool steels are tabulated below.
