Tungsten Based High Speed Steel

Tungsten Based High Speed Steel The term high speed steel was derived from the fact that it is capable of cutting metal at a much higher rate than carbon tool steel and continues to cut and retain its hardness even when the point of the tool is heated to a low red temperature. High working hardness-high-speed tools steels can be hardened to 62-67 HRC . High speed steel can be bifurcated on the basis of the alloying elements, even though their applications remain quite similar. Applications Turning toolsPlanning toolsSlotting toolsTapsTwist drillsLathe toolsSawsHobsChasersProfile cutting toolsBroaching toolsReamersCold extrusion diesPunchesTool bits High speed steels is being offered in conventional as well as ESR route. With continuous improvements and research in tool steels, there is an invent of HSS produced by power metallurgy. This offers combination of unique properties Higher ToughnessHigher Wear ResistanceHigher HardnessHigher Hot Hardness The advantage of using powder metallurgy High Speed Steel is that it provides prolonged tool life, makes tool life more predictable, improves performance. Qualities High speed steels offer higher bend strength than any other cutting materials, which provides better cutting resistance to edge chipping, extended cutting depth, i.e. fewer cuts, increased feed per tooth.It can maintain high hardness at service temperature as wellHigh wear resistance
