Abstract

The invention provides a preparation method of a GH4098 alloy plate, which comprises: vacuum induction melting and vacuum consumable melting of alloy raw materials to obtain a steel ingot; forging, rolling and heat treatment of the steel ingot to obtain a GH4098 alloy plate. The invention adopts a new preparation method of GH4098 (GH98) alloy, so that the performance of GH4098 (GH98) alloy plate is qualified, meets the standard requirements, improves product quality, creates more economic benefits for enterprises, and makes greater contributions to national defense. . The invention also provides a GH4098 alloy plate.

Description

technical field [0001] The invention belongs to the technical field of alloy plates, in particular to a GH4098 alloy plate and a preparation method thereof. Background technique [0002] Due to the accelerated upgrading of the aviation industry, high-temperature alloy plates with better performance are required to replace old alloy grades such as GH3044, GH3128, GH536, etc. When GH4098 (GH98) is used below 950°C, it has high strength and plasticity, and is mainly used as a load-bearing part for working conditions below 950°C. But the performance of GH4098 alloy plate still needs to be further improved. Contents of the invention [0003] In view of this, the object of the present invention is to provide a GH4098 alloy plate and a preparation method thereof. The GH4098 alloy plate prepared by the method provided by the present invention has better properties. [0004] The invention provides a method for preparing a GH4098 alloy plate, comprising: [0005] Vacuum induction...
