Introduction

HSS M2(1.3343) has the both Tungsten series and Molybdenum series features, the hardness and high temperature hardness is better. M2( 1.3343) has the advantages of small carbide particles and uniformity, the toughness is significantly enhanced than other normal steel. As the high vanadium content the wear resistance is also better. Due to the superior performance mentioned above, M2 (1.3343) is widely used in global nowadays.
