Duplex Stainless Steel Ground Bars
2205 Duplex Stainless Steel Bar AISI 2205 | UNS S32205
Weight reduction and corrosion resistance are both important in many high-strength industrial components. 2205 duplex stainless steel provides yield strength more than twice that of many standard austenitic stainless steels, allowing designers to reduce material weight while maintaining reliable structural performance.
Its balanced austenitic-ferritic structure gives 2205 strong resistance to chloride corrosion, good low-temperature impact toughness, and higher mechanical strength than common austenitic stainless steel grades. These advantages make it suitable for components used in wastewater treatment systems, pulp and paper equipment, high-strength rotating shafts, and corrosion-resistant industrial assemblies.
Compass Power Tech manufactures 2205 duplex stainless steel precision ground bars for customers who need accurate dimensions, stable surface quality, and dependable performance in high-strength and chloride-containing environments.

Additional Custom Services
- Cut-to-length service: Shaft length can be customized according to customer assembly requirements.
- End chamfering: Both ends of the shaft can be chamfered to simplify downstream machining and installation.
- Drawing-based machining: Shafts can be machined according to customer drawings and supplied as ready-to-assemble components.
- Surface rolling treatment: Surface rolling can be applied to improve surface hardness when higher wear resistance is required.
Packaging and Storage
To protect stainless steel precision ground shafting during sea freight and storage, Compass Power Tech uses anti-rust paper tube packaging. Before wrapping, anti-rust oil is applied evenly to the shaft surface, and anti-rust wax is applied inside the paper tube. This protection process helps reduce corrosion risk during transportation and ensures customers receive shafts in stable, ready-to-use condition.
