Definitions

  • This invention relates to non-ledeburitic high-speed steels containing as the main alloying component tungsten and /or molybdenum.
  • the above mentioned steels can contain the following amounts of other constituents by weight: 1.2 up to 2.3 per cent of carbon, 3.0 up to 7.0 per cent of chromium, 1.0 up to 1.3 per cent of vanadium, up to 1.5 per cent of manganese, 0.2 up to 0.5 per cent of zorconium, 0.4 up to 1.5 per cent of silicon,up to 0.4 per cent of nickel, up to 0.03 per cent of sulphur, up to 0.03 per cent of phosphorus, up to 1.5 per cent of titanium and/or niobium and other elements in the form of unavoidable impurities.
  • the nature of the invention comprises to introduce in steel another steel containing by weight 6.0 to 7.0 per cent of tungsten, or 5.0 to 6.0 per cent of molybdenum, or 1.0 to 6.0 per cent of tungsten and molybdenum totally, and moreover, 1.2 up to 1.3 per cent of vanadium, up to 1.5 per cent of manganese, 0.2 up to 0.5 per cent of zirconium, 0.4 up to 1.5 per cent of silicon, up to 0.4 per cent of nickel, up to 0.03 per cent of sulphur, up to 0.03 per cent of phosphorus and some other elements in the form of unavoidable impurities, as well as 1.5 up to 6.0 per cent of titanium and niobium totally with the properly balanced carbon content acc.
  • Steels acc. to the invention contained in the casting form no carbon eutectics. Moreover, these steels does not exhibit, both after having been cast or plastic worked, any macro- or microsegregation of carbides. After final heat treatment, the structure of these steels exhibits a uniform distribution of primary carbides of titanium, niobium and zirconium, as well as secondary carbides containing mainly tungsten, molybdenum and vanadium in tempered martensite matrix and a small amount of retained austenite.
