ASG News: according to Northeast Special Steel Group news, recently, Fushun Special Steel successfully produced thick 55mm, wide 600mm GH4099 superalloy wide thick plate, after inspection, the product size, shape, surface quality and mechanical properties and other indicators meet the requirements of the technical standard. The successful production of this product has attracted the close attention of users in the aerospace field, and then some users put forward the demand for the development of 90mm thick GH4099 superalloy sheet to Fushun Special Steel Company, which laid a solid foundation for the company to further expand the field of superalloy products.

GH4099 is a nickel-based superalloy, its initial research and development is mainly used in the aviation field, the products are mainly small size cold rolled sheet. In recent years, GH4099 superalloy has been widely used in the aerospace field, the size and specification of the plate has also increased greatly, especially the width and thickness, and the aerospace design department has revised the GH4099 superalloy standard many times, and the high temperature tensile strength and plasticity index of the products have also been improved. Therefore, the technical difficulty and risk of R & D and production of GH4099 superalloy are very great.
