Material description: W6M05Cr4V2 (M2) is China's typical W-Mo high-speed steel. The addition of 1% molybdenum can replace 2% of tungsten, and the addition of molybdenum reduces the alloying elements in the steel, thus reducing the inhomogeneity of the number and distribution of carbides and refining the grain. Compared with W18 steel, the bending strength of M2 steel increases by about 17%, the impact toughness increases by more than 40%, and the large section tool also has the same strength and toughness. It can be used to manufacture tools with larger cross section or tools with larger impact force. It added that even the same material, may also be due to different manufacturers, because of its quenching technology and groove process, cause the tool performance of different.
