    1. Scope

    1.1 This specification covers tungsten-type and molybdenum-type high-speed steels available as annealed, hot-rolled bars, forgings, plate, sheet, or strip, and annealed, cold-finished bars or forgings used primarily in the fabrication of tools.

    1.2 Seven types of tungsten high-speed tool steels designated T1, T2, etc., seventeen types of molybdenum high-speed tool steels designated M1, M2, etc., and two intermediate high speed steels designated as M50 and M52 are covered. Selection will depend upon design, service conditions, and mechanical properties.

    1.3 The term "high-speed steel" is described and its minimum requirements are covered in the Annex.

    1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.
