W2Mo9Cr4Co8 is a high-speed steel, cobalt toughness, wear resistance is mainly used for high-precision metal toughness Die, can also be used to cool the cutting tools and knives. High steel hardness up to 70HRC, hot hardness, high temperature hardness, easy grinding. With the steel cutting tools, you can cut the iron-base superalloys, superalloy, titanium and ultra high-strength steel, but the toughness somewhat less, should be used when the quenching temperature limit. As the good grinding performance, so can be used to manufacture a variety of high-precision complex tools.
