310MoLN UREA stainless steel seamless pipe, forged stainless steel plate in stock

Short Description:

1.4466 – UREA 25.22.2 -310MoLN – UNS S31050 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 stripper.

1.4466, X1CrNiMoN25-22-2, AISI 310MoLN – specification and application.

High-nickel austenitic stainless steel for parts and components of chemical apparatus used mainly in the production of urea. The grade is suitable for working at elevated temperatures. 1.4466 steel is used in the paper, nitrogen, pharmaceutical, petrochemical and cellulose industries.
