Product Details

ASTM A240/A240M 321 347 Polishing Round Bar 400 Outer Diameter 6000mm Length

Duplex stainless 2205 (UNS S32205) is a chromium-nickel- molybdenum-nitrogen stainless steel. UNS S32205 has high strength and corrosion resistance at temperatures up to 316°C. UNS S32205 is a duplex grade with a ferritic-austenitic microstructure. The alloy consists of around 40-50% ferrite in the annealed condition.

If the 2205 is greater than about 0.625 inch (16 mm) thickness, and welding is to be done with very low heat input (≤12 kJ/inch, 0.5 kJ/mm), preheating to the range of 200–300°F (95–150°C) can be useful. The purpose of this preheating is to avoid excessively rapid cooling and a resulting extremely high ferrite content.

Duplex SS are two-phase alloys containing equal proportion of ferritic and austenitic phases in their microstructure, providing a combination of the corrosion resistance of austenitic stainless steels with greater strength.
