The Duplex UNS S31803 grade is the most frequently used duplex grade. The grade generally has a higher corrosion resistance compared to the austenite steels. The grade also has a yield strength, double that of conventional austenitic stainless steels.
The designation 2205 reflects the amounts of chromium (22%) and nickel (5%) in the alloy.The chemical composition range that was first set for SAF 2205 (UNS S31803), was found to be too broad. The composition was modified to optimize corrosion resistance and to avoid inter-metallic phases. The modified version of SAF 2205 (UNS S32205), has a tighter range for chromium, molybdenum and nitrogen in the higher end of the original range.
Because of it’s good corrosion resistance, high yield strength and weldability, SAF 2205 is used within a wide range of different industries and applications. In the oil and gas industry duplex 2205 is used in: Pipes, valves, pumps, Xmas trees, bolting, connectors, manifolds and more.
As with most steel plate products a number of different designations are used for these steels. The most common are:
The material on stock corresponds with UNS S32205, UNS S31803, W.nr 1.4462 and of course SAF 2205. Our material is NORSOK approved, implying a 3.2 certification and is in accordance with NACE MR0175.
