Abstract

The invention relates to an alloy for producing objects with high heat resistance and ductility. Furthermore, the invention relates to a hot-forging steel object with high hardness, high heat resistance and high thermal stability. To improve the property profile at high processing temperatures, it is provided according to the invention that a preliminary material, preferably with a composition in % by weight of: Carbon (C) ~ 0.15 to 0.44 Silicon (Si) ~ 0.04 to 0.3 Manganese (Mn) ~ 0.05 to 0.4 Chromium (Cr) ~ 1.2 to 5.0 Molybdenum (Mo) ~ 0.8 to 6.5 Nickel (Ni) ~ 3.4 to 9.8 Vanadium (V) ~ 0.2 to 0.8 Cobalt (Co) ~ 0.1 to 9.8 Aluminum (Al) ~ 1.4 to 3.0 Iron (Fe) ~ remainder is shaped into an object by hot-forming and processing and that this object has secondary precipitated carbides and intermetallic precipitations in the structure after a heat treatment.
