DEF

An alloy steel that remains hard and tough at red heat.

Modern high-speed steel can be used at six or seven times the cutting speeds possible with carbon-tool steels, and the cutting edge can be allowed to reach a red heat. These steels contain tungsten, chromium and vanadium and may also contain either molybdenum or cobalt. When forged and annealed, they are soft and can be machined easily into complex forms.

OBS

high-speed steel: term officially approved by the Lexicon Project Committee (New Brunswick).
