Abstract
A description is given of a temperature-stable cast-iron alloy having high wear resistance at temperatures between 500 and 900° C. The alloy is characterized in that it has the following composition expressed in weight percentages: chromium: 15.0-20.0%, carbon: 1.0-2.0%, manganese: 1.5-2.0%, silicon: 0.8-1.2%, nickel: 8.0-10.0%, molybdenum: 0.8-1.2% balance iron and unavoidable metallic and non-metallic contaminants where the non-metallic contaminants comprise nitrogen, oxygen, phosphorous and sulphur. Hereby is obtained a cast-iron alloy which has a higher wear resistance and a reduced tendency to form the undesirable sigma phase when heated to temperatures between 500 and 900 ° C. as compared to the known allows.
