MB60 MB60 carbide grade hardness HRA ≥ 83 Bending strength toughness TRS ≥ 2500 N/mm2 ≥ 9.5 Features: Is the improved YG20C new grades, wear resistance under the premise of ensuring improved strength and toughness. Because of its fine grain tungsten steel, the blade can be sharpened, smooth; also because of its strength and hardness are high, and therefore a long time to maintain edge roughness and small radius. Therefore, in the processing of heat-resistant alloy, use YS2, YM051, YM052, YD05 other than the use of ultra-fine grain carbide YT, YG, YW three ordinary carbide has good heat resistance and integrated wear, not only its significantly improved tool life and cutting efficiency several times, and the surface roughness of the workpiece was also significantly reduced. It can be widely used.
