PM M48 High Speed Steel


PM M48 is a flexible high-speed steel steel with a unique combination of high wear-resistance, high-impact toughness, and bend strength, which are results of its fine grain size, small carbides, superior cleanliness, and addition of tungsten, molybdenum, and cobalt. PM M48 offers higher cutting speeds, extended tool life, and good machineability compared to conventional high-speed steels like M2.
