High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material. 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 … See more In 1868 English metallurgist Robert Forester Mushet developed Mushet steel, considered the forerunner of modern high-speed steels. It consisted of 2% carbon, 2.5% manganese, and 7% tungsten. The major advantage of … See more High speed steels are alloys that gain their properties from a variety of alloying metals added to carbon steel, typically including tungsten and … See more HSS drill bits formed by rolling are denoted HSS-R. Grinding is used to create HSS-G, cobalt and carbide drill bits. See more • Chromium-vanadium steel (Cr-V) • List of steel producers See more Lasers and electron beams can be used as sources of intense heat at the surface for heat treatment, remelting (glazing), and compositional modification. It is possible to achieve different … See more The main use of high-speed steels continues to be in the manufacture of various cutting tools: drills, taps, milling cutters, tool bits, hobbing (gear) cutters, saw blades, planer and jointer blades, router bits, etc., although usage for punches and dies is … See more WebDec 9, 2024 · Deformation-induced carbide transformation (DICT) is first observed in M2 high-speed steel (HSS) wherein deformation enables a lower transformation temperature and enhanced transformation rate of M 2 C carbide into M 6 C and MC. Dislocations introduced into M 2 C by pre-deformation act as nucleation sites of new precipitates and …
