Mold for hot forging, method for producing forged product using the same, and method for producing hot forging die

摘要

A hot forging die made of a Ni-base superheat-resistant alloy, which does not cause deterioration of the working environment and shape during hot forging in the atmosphere, a method for producing a forged product using the same, and heat A method for producing a die for hot forging is provided. In mass%, W: 10.3-11.0%, Mo: 9.0-11.0%, Al: 5.8-6.8%, and the balance is Ni and inevitable impurities It has a base material composition made of a Ni-base superalloy, has a coating layer of an inorganic material on at least one of a molding surface and a side surface, and the coating layer is one or more of Si, Cr, and Al among Si and metal elements A die for hot forging containing 30% by mass or more in total.
