GH4169 material specification
Hot rolled rod: 10-100mm, forged rod: 100mm~350mm, cold rolled sheet: 0.05mm-4.0mm, hot rolled plate: 4mm-14mm, with 2mm~10mm, forging rings of various sizes and specifications, and individual grades in stock are variable.
GH4169 Processing and Welding Performance
The alloy has satisfactory welding performance, and can be welded by argon arc welding, electron beam welding, seam welding, spot welding, and other methods. For directly aged components, inertial friction welding can be performed in the forged state, and after welding, direct aging treatment can be performed to obtain joints with high endurance strength.
