摘要： A nodular graphite, heat-resistant cast iron composition for use in engine systems. The composition contains carbon 1.5-2.4 weight %, silicon 5.4-7.0 weight %, manganese 0.5-1.5 weight %, nickel 22.0-28.0 weight %, chromium 1.5-3.0 weight %, molybdenum 0.1-1.0 weight %, magnesium 0.03-0.1 weight %, and a balance weight % being substantially iron. The composition has an austenitic matrix. Additionally, the composition exhibits excellent oxidation resistance at high temperature and excellent mechanical properties at both room and high temperatures. Thus, the composition can be a lower cost substitute material for Ni -Resist D5S under thermocycling conditions experienced by exhaust gas accessories and housings such as engine exhaust manifolds, turbocharger housings, and catalytic converter housings.

摘要： A nodular, compacted graphite or other hybrid or duplex graphite morphology cast high silicon iron is disclosed which contains up to 1.5% tungsten, up to 0.8% vanadium, and up to 1.2% niobium; and at least 60.0% iron, all percentages are based on the total weight of the composition. This cast iron exhibits high strength and good ductility over a wide temperature range compared to the conventional SiMo ductile iron. The compositions may further contain, up to 1.5% molybdenum and up to 1.0 % chromium to offer improvements in material strength. The compositions may include 0.2 to 0.5% by weight aluminum and up to 1.2% chromium for further oxidation resistance and 0.5 to 5.0% nickel for corrosion resistance.
