About 310MoLN Austenitic Stainless Steel
What is 310MoLN Austenitic Stainless Steel?
310MoLN stainless steel is the low-carbon version of 310L modified austenitic stainless steel. It is also referred to as the UNS S31050 / W.Nr. 1.4466 stainless steel.
310MoLN 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 content in order to stabilize and strengthen the austenitic phase.
The alloy is designed to obtain a fully austenitic stainless steel free of intermetallic phases as intergranular carbide precipitations which affect drastically 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).
