Hot Rolled EN 1.4466 Stainless Steel Pipe AISI310MoLN / S31050 Stainless Steel Tubing
1.4466 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 UNS S31050 is designed for the fabrication of lining interiors in Urea units or complementary products (pipes, fittings…). The grade can be used for urea strippers.
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.

Mark details on the pipe
HOT FORMING
Hot forming should be carried out in a temperature range of 1200 - 950°C (2732 - 1742°F) after the piece has been uniformely heat treated. Final full annealing temperature is required to obtain the requested microstructure. It will be performed at 1140° - 1180°C (2084 - 2156°F) followed by water quenching.
COLD FORMING
Due to its fully austenitic microstructure, the alloy can be cold formed without any problem. The higher molybdenum content and cold hardening behaviour of the steel explains that it may require more powerfull equipments than 304 stainless steel.
PICKLING
310Mo LN grade must be used in the as pickled and passivated conditions. Pickling treatment may be performed with a nitro - hydrofluoric acid bath (10 - 20% HN03 - 1.5 - 5% HF) at 40 - 60°C (104 - 140°F). A 10 - 20% H2SO4 - 1.5 - 5% HF pickling bath may also be used.
WELDING
310Mo LN can be welded with most of the welding processes: TIG, Plasma, MIG welding, as well as SMAW, SAW or FCAW processes. The alloy is sensitive to hot cracking phenomenon due to its fully austenitic microstructure. Weld should be performed in order to obtain extra - low ferrite contents, no carbide or nitride precipitations, low silicon contents as well as no intermetallic phase precipitations. Higher manganese content products should be considered.
Typical Applications:
- Urea applications
- Pulp & Paper industry
- Flue gas cleaning
- Chemical industry
- Pharmaceutical industry
