UREA 25.22.2 chemical composition has been optimised for specific uses in Urea plants. It is a 310L modified austenitic stainless steel with low carbon, low
silicon and high nitrogen additions in order to stabilize and strengthen the austenitic phase. The alloy is particularly designed for improved corrosion resistance properties in urea carbonate environments including strippers. The grade is also well designed for resistance in wet corrosive conditions due to its high contents of chromium, molybdenum and nitrogen (PREN > 33). UREA 25.22.2 is designed for the fabrication of lining interiors in Urea units or complementary products (pipes, fittings…). The grade can be used for urea strippers.

Technical characteristics

Stainless chromium-Nickel low-carbon austenitic steel. Specific gravity 7.9 g/cm³. The alloy additionally alloyed with molybdenum, manganese, silicon, demonstrates improved strength over a wide temperature range. The temperature of beginning of intensive formation of scale 1050 °C.
