2205 round bars, a duplex stainless steel (UNS S32205), combine austenitic and ferritic phases to deliver unmatched strength and corrosion resistance for demanding industrial applications. With a 50:50 phase balance, this alloy offers twice the yield strength of 316 stainless steel (minimum 450 MPa) while maintaining excellent ductility (over 25% elongation). Newstar Hardware's 2205 round bars, manufactured to ASTM A276 and A479, are available in diameters from 8 mm to 200 mm, suitable for high-pressure piping, marine structures, and chemical processing equipment. The dual-phase microstructure enhances resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride environments, outperforming austenitic grades in seawater, wastewater, and oil & gas applications. Its corrosion resistance index (PREN > 34) makes it ideal for offshore platforms, heat exchangers, and desalination systems. The alloy's magnetic permeability and thermal conductivity properties suit it for precision instruments and heat transfer components. Fabrication-friendly features include good weldability (with post-weld heat treatment options) and machinability, while rigorous testing (ferrite content analysis, impact testing) ensures compliance with international standards for safety-critical applications.
