ABSTRACT:
This invention relates to high-Cr precision casting materials containing carbon, silicon, manganese, chromium, nickel, vanadium, niobium, nitrogen, molybdenum, tungsten, cobalt and optionally boron in specific weight proportions, the balance being iron and incidental impurities, as well as turbine blades made by a precision casting process using these materials. Thus, the present invention provides high-Cr precision casting materials which are capable of precision casting and, moreover, have excellent high-temperature strength, as well as inexpensive and highly reliable turbine blades made by using these casting materials and such turbine blades also having lighter weight.
