High Speed Steel

High speed steel (HSS or HS) is a subset of tool steels, commonly used in tool bits and cutting tools. It is often used in power saw blades and drill bits. It is superior to the older high carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high speed steel. At room temperature, in their generally recommended heat treatment, HSS grades generally display high hardness (above HRC60) and a high abrasion resistance (generally linked to tungsten and vanadium content often used in HSS) compared to common carbon and tool steels.

Famous quotes containing the words steel, high and/or speed:

    The tyrant custom, most grave senators,
    Hath made the flinty and steel couch of war
    My thrice-driven bed of down.
    William Shakespeare (1564–1616)

    No men who really think deeply about women retain a high opinion of them; men either despise women or they have never thought seriously about them.
    Otto Weininger (1880–1903)

    The correct rate of speed in innovating changes in long-standing social customs has not yet been determined by even the most expert of the experts. Personally I am beginning to think there is more danger in lagging than in speeding up cultural change to keep pace with mechanical change.
    Mary Barnett Gilson (1877–?)
