Classification of powdered high-speed steel

According to the engineer's introduction, the powder high-speed steel made of traditional high-speed steel and the difference lies in the difference in manufacturing procedures, and add some insufficient metal elements, can also be melted according to the demand for a variety of constituent elements of steel. Generally and traditional high-speed steel is divided into Mo (molybdenum) system and W (tungsten) system of two large systems. Mo system of material toughness is better, W system of material wear resistance is better, high-temperature hardness is higher, impact resistance is stronger.
