X11CrMoWVNb9-1-1 is high-temperature resistant, martensitic (structure of heat-treatable material used) high-alloyed chromium-molybdenum-steel, which is used for mixed-pressure turbine elements by improved properties compared with common steel (10CrMo9-10). With its higher amount of  chrome and molybdenum together with nitrogen (0,03-0,07%) and vanadium (> 0,18 %) it is possible to substitute nickel it still work at more than 500°C in permanent load,This grade is characterized by good mechanical behavior (creep yield strength and creep rupture strength) under long-term conditions at temperatures ≥ 500°C. Applications: power plant construction, mechanical engineering, power generation, fittings and accessories in boiler construction motor and furnace manufacturing
