Abstract

A nickel-based superalloy is provided. Known nickel-based superalloys for producing components made of stem shaped single crystals do not provide sufficiently for grain boundary strength. The superalloy includes a low molybdenum content and very accurately adjusted values for elements having grain boundary strength and elements that precipitate in grain boundaries.
