Urea 25.22.2 Fasteners & Machined Components

UREA 25.22.2 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.


Urea 25.22.2 Studs, Hexagon Bolts (sets) & Nuts

25.22.2 is designed to obtain a fully austenitic stainless steel free of intermetallic phases as intergranular carbide precipitations which affects the corrosion resistance properties of the alloy in urea containing solutions. The ferrite level is kept under 0.5% in the solution annealing and water quenched conditions. 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)


The alloy is used across several applications including urea fertilizer units, strippers, nitric acid, sulphuric acid, and in gas treatment plants :
