Overview
2205 Duplex Stainless Steel Plate combines higher strength with improved chloride stress-corrosion resistance relative to common austenitic grades in many process and marine-adjacent duties. Buyers should confirm ASTM A240 / EN duplex practice, thickness, surface condition, welding procedure requirements, and EN 10204 3.1 chemistry including PREN-related elements. 2205 is not a drop-in substitute for 316L without fabrication and welding review.
