Abstract (en)
[origin: US4435226A] A wear resistant cast iron alloy having a great strength for the manufacture of wear resistant machine parts having a tempered structure with embedded graphite spheroids formed in very fine form by the decomposition of ledeburite. The alloy has a spheroid number of 300,000 to 900,000/cm2 and is comprised of 1.5 to 3.0% carbon, 3.0 to 6.0% silicon, 0.1 to 2.0% manganese, 0.05 to 0.5% phosphorus, up to a maximum of 0.15% sulfur, 0.1 to 1.0% chromium, 0 to 3.5% vanadium, 0.1 to 2.5% molybdenum, 0.1 to 3.0% nickel and/or cobalt, 0.1 to 3.5% copper, 0.1 to 2.5% tungsten, 0.1 to 1.0% titanium, niobium and/or tantalum, up to a maximum of 0.15% magnesium, and up to a maximum of 0.15% nitrogen. A method is provided for producing a cast piece of the cast iron alloy.
