Duplex stainless steel combines ferritic and austenitic structures, giving customers a material option that brings together strength, toughness, corrosion resistance, and weldability. This balanced structure makes duplex grades especially valuable for precision shaft applications exposed to chloride-containing media, corrosive fluids, or higher mechanical loads.

Compared with ferritic stainless steel, duplex stainless steel offers better plasticity, toughness, intergranular corrosion resistance, and welding performance. Compared with many austenitic stainless steel grades, it provides higher strength and stronger resistance to chloride stress corrosion cracking, helping customers improve component reliability in more demanding environments.

Compass Power Tech manufactures duplex stainless steel precision ground bars in S31803, S32205, S32750, and S32760 grades. These materials are suitable for corrosion-resistant shafts, hydraulic and pneumatic components, pump and valve parts, marine-related components, chemical processing equipment, and other applications where strength and corrosion resistance must work together.
