Title: STEEL MATERIAL FOR HIGH-TEMPERATURE APPLICATIONS, AND TURBINE CASING MADE OF SAID MATERIAL
Abstract:
The invention relates to a steel material (21a) for high-temperature applications as well as to a turbine casing (21) for a turbocharger (1) made of said steel material (21a), the steel material (21a) being characterized by a material composition containing specific amounts at least of the alloying components carbon, silicon, manganese, chromium, nickel, niobium and iron. The disclosed material composition ensures sufficient temperature resistance while having a lower nickel content and being less expensive than other high-temperature materials.
