What Is a Duplex 2205 Shaft Used For?
2205 forged shafts are widely used in applications requiring both high strength and outstanding corrosion resistance, including:
Why Choose Forging Instead of Machining from Bar Stock?
Forging improves the internal grain flow of the metal, resulting in:
Higher fatigue strength
Better impact resistance
Improved load-bearing capacity
Reduced risk of internal defects
Longer service life
Better reliability for rotating equipment
These advantages are especially valuable for shafts operating under continuous torque, cyclic loading, or corrosive service conditions.
