Patent number: 8454764Abstract: 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.Type: GrantFiled: February 25, 2008Date of Patent: June 4, 2013Assignee: Wescast Industries, Inc.Inventors: Robert Logan, Delin Li, Shuzhi Yu, Gangjun Liao
