Research on Al and Ti Element Control Technology of High-Temperature Alloy H80A Steel
High-temperature alloys have excellent high-temperature mechanical properties,structural stability,and resistance to hot corrosion,which can work reliably in high temperature and complex stress environments for a long time and are widely used in the manufacturing of hot end components for aviation,aerospace,and ship engines.Taking high-temperature alloy H80A steel as an example,this paper analyzes the changes in Al and Ti elements during vacuum melting and electroslag remelting processes,and then proposes effective measures for controlling Al and Ti elements.After taking targeted measures,the composition control ability of H80A steel has been improved,and the product quality has been significantly improved.
