Abstract

The present invention relates to an Ni-based superalloy for hot forging, containing, in terms of % by mass, C: more than 0.001% and less than 0.100%, Cr: 11% or more and less than 19%, Co: more than 5% and less than 25%, Fe: 0.1% or more and less than 4.0%, Mo: more than 2.0% and less than 5.0%, W: more than 1.0% and less than 5.0%, Nb: 0.3% or more and less than 4.0%, Al: more than 3.0% and less than 5.0%, Ti: more than 1.0% and less than 3.0%, and Ta: 0.01% or more and less than 2.0%, with the balance being unavoidable impurities and Ni, in which the component composition satisfies the following two relationships: 3.5≤([Ti]+[Nb]+[Ta])/[Al]×10<6.5 and 9.5≤[Al]+[Ti]+[Nb]+[Ta]<13.0.
