Abstract: A bimetal saw band which is suitable for cutting materials of high hardness and wear resistance at high cutting speeds and with a reduced consumption of coolant is disclosed. The saw band includes a support band with from 0.20 to 0.45% of carbon, from 0.2 to 0.6% of silicon, from 0.5 to 1.8% of manganese, from 0.1 to 3.5% of molybdenum, from 1.0 to 5.0% of chromium, from 0.5 to 1.5% of nickel, from 0.1 to 1.0% of copper, from 0.1 to 2.0% of tungsten, from 0.1 to 0.5% of vanadium, from 0.01 to 0.30% of niobium and/or tantalum and less than 0.2% of cobalt, and the remainder iron including melting-related impurities, with the tungsten, vanadium and niobium/tantalum contents matched to one another. The saw includes hardmetal tips including at least 75% of tungsten carbide and 5 to 15% of cobalt, as well as grain stabilizers with a grain size of less than 5 ?m.

Abstract: A chromium steel alloy comprising 0.25 to 0.35% of carbon, 0.3 to 0.5% of silicon, 0.8 to 1.5% of manganese, 1.0 to 2.0% of molybdenum, 1.5 to 3.5% of chromium, 0.5 to 1.5% of nickel, 0.5 to 2.5% of tungsten, 0.15 to 0.30% of vanadium and/or 0.05 to 0.10% of niobium, 0.05 to 1.0% of copper, 0.01 to 0.2% of aluminum and 0.01 to 1.0% of cobalt, remainder iron is distinguished by a high resistance to hydrogen embrittlement and is therefore particularly suitable for use as a material for objects coated electrolytically, by PVD or by CVD, for example for saw blades with hard-material particles intercalated into the coating.

Abstract: In a method of producing saw bands and saw blades with improved dimensional and setting stability, a supporting band (2) with 0.2 to 0.6% carbon, 0.5 to 6.0% chromium and up to 3.5% tungsten, molybdenum and vanadium—individually or in addition to one another—the remainder being iron, is welded to a cutting band (3) of a high-speed steel and the weld (4) is thereby adjusted to a ratio of its average width to the thickness of the band or blade of 0.30 to 0.9.
