High Speed Steel Product Introduction
M-2 is a tungsten-molybdenum high-speed steel. It is a commonly used steel grade for both cutting and non-cutting applications. M2 has a higher carbon content compared to M1 tool steel, providing greater wear resistance for applications requiring wear resistance. M2 HSS has a wider range of heat treatments than most molybdenum HSS. In addition, M2 steel also has the unique decarburization resistance of tungsten steel, and M2 steel also perfectly combines red hardness, toughness and wear resistance.
M2 HSS is a balanced composition suitable for a variety of applications and has replaced T1 HSS in most applications due to its superior performance and relative economics.
In the annealed condition, M2 grade steel is considered a medium-duty tool steel. The term high-speed steel comes from M2's ability to withstand higher temperatures without losing hardness. Therefore, it can withstand the heat generated at higher processing speeds.
