Abstract

Disclosed is a powdered high speed tool steel of good wear resistance and toughness. The powdered high speed tool steel have the alloy composition essentially consisting of 1.2 - 4.5 % of C, up to 3.0 % of Si, up to 3.0 % of Mn, 3.0 - 6.0 % of Cr, 15.0 - 60.0 % of W (up to 30.0 % thereof may be replaced by Mo), 1.0 - 15.0 % of V and up to 20.0 % of Co, and the balance substantially of Fe, and the carbide particles in the steel is relatively large, and those having Heywood diameters 1 micron or more share at least 10 volume % of the whole carbide particles.
