Annealed ferritic material useful for valve seat rings and turbocharger components, comprises carbon, chromium, molybdenum, vanadium, silicon, manganese, iron, production-related impurities and other elements

摘要

Annealed ferritic material for valve seat rings and turbocharger components, comprises (in wt.%) carbon (1.5-3.5), chromium (28-37), molybdenum (3-8), vanadium (1.5-5.5), silicon (1.5-4), manganese (0.2-1.5), iron (remaining amount), production-related impurities and other elements. An independent claim is also included for producing the annealed ferritic material, comprising (a) metallurgically producing an alloy comprising the above material composition, and (b) annealing the alloy at 550-750[deg] C for 1-3 hours.
