Nickel Alloy Steel Forged Bars

Forged bars are high-quality bars processed through forging technology, featuring dense internal structure, excellent mechanical properties, and good ultrasonic testing pass rates. They are widely used in critical load-bearing components in pressure vessel manufacturing, nuclear power equipment, petrochemical industry, heavy machinery, and aerospace industries. The nickel alloy forged bars supplied by Hefei Tailan Metal Co., Ltd. are manufactured from high-quality nickel-based alloy ingots or continuous casting billets through multiple precision processes including heating, forging, heat treatment, inspection, and machining. Featuring dense structure, no internal defects, uniform properties, and large forgeable sizes, they are specifically designed for demanding applications with extremely high requirements for internal quality and mechanical properties.

Forging Process Advantages:

1. Open Die Forging: Suitable for single piece, small batch, large size bars
2. Closed Die Forging: Suitable for mass production, complex shape bars
3. Rotary Forging: Suitable for high precision, slender bars
4. Upsetting+Drawing: Fully breaking as-cast structure, improving isotropy
