The 310MoLN grade has an optimized chemical composition for specific applications in urea plants. Carbon content is low and chromium and nickel have respective levels of 25% and 22%. Moreover, silicon content is also low and nitrogen is added to this chemical composition, which stabilizes and strengthens the austenitic phase.
Heat Resistance. Grade 316L is more resistant to carbide precipitation and can be used in the above temperature range. Grade 316H has higher strength at elevated temperatures and is sometimes used for structural and pressure-containing applications at temperatures above about 500 C.
Safurex is a better choice than 316L Urea Grade and 2RE69 for usage in strippers, H.P. condensers, scrubbers, high-pressure piping and reactors. Tube, pipe, fittings, plate, bar and welding consumables are available for fabrication of new or replacement units.

Urea, also known as carbamide, is an organic compound with chemical formula CO(NH 2) 2. This amide has two NH 2 groups joined by a carbonyl (C=O) functional group . Urea serves an important role in the metabolism of nitrogen -containing compounds by animals and is the main nitrogen-containing substance in the urine of mammals .
316L modified (724L)---Urea grade stainless steel . Character of 316L modified (724L): The alloy is designed for urea applications (low carbon and silicon contents). The 316L Modified grade can be welded with most of the welding processes: TIG, Plasma, MIG welding, as well as SMAW, SAW or FCAW processes.
The best known grade is Type 304, also known as 18/8 and 18/10 for its composition of 18% chromium and 8%/10% nickel, respectively. The second most common austenitic stainless steel is Type 316 . The addition of 2% molybdenum provides greater resistance to acids and to localized corrosion caused by chloride ions.
Technical data and information are to the best of our knowledge at the time of publication. However, they may be subjected to some slight variations due to our ongoing research programmes.

1.4404, 1.4401, AISI 316/L - application and specification. Austenitic stainless steel is resistant to intergranular corrosion, used mainly in environments containing harmful chlorides, acids and urea. 316/316L is the basic grade from the CrNiMo group with Molybdenum, the addition of which significantly increases the resistance to pitting and crevice corrosion of steel by 2-3 times.
Data to be selected as for grade Sanmac 316/316L, taking into account the above comments. Forms of supply Sandvik 2RE69 seamless tube and pipe is supplied in dimensions up to 355 mm (14.0 in.) outside diameter in the solution annealed and white pickled condition, or solution annealed by a bright annealing process.
Although they come from the same chemical compounds, the higher grade, environmental urea is stripped of all contaminates since the Selective Catalytic Reduction (SCR) system cant tolerate them. While the fertilizer grade urea is solutionized with other chemicals including formaldehyde, allowing it to become a solid, making it easier to , urea grade 316l chemical composition

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.
RE: Excessive Corrosion of 316L (Urea Grade) in Carbama Asfaqanver Ferrite number 8 is high. Usually with higher ferrite (delta ferrite in welds) corrosion resistance will be lower and also possibility of the weld metal composition may not ideally match the Urea grade S.S 316 L.
Chemical compositions of AISI (ASTM/ASME) and UNS austenitic stainless steel grades Introduction - AISI ASTM ASME and UNS. Most ASTM and ASME standards list the steel grades by their UNS (Unified Numbering system) numbers but also make reference, where appropriate to the more general AISI (American Iron and Steel Institute) grade designations.
and gas lines fabricated from urea grade 316L. Such corrosion can be prevented by adequate insulation and tracing. When condensation forms part of the process, as in the HP carbamate condenser, special technological measures must be taken. One such measure is adding an oxy-gen-rich liquid phase containing a metal ion
Whether 316L can be used depends on the amount of alloying elements and mainly Cr and Mo play a very important role and of course the Carbon content, the higher the Cr content in combination with a low Carbon content gives the best results and that is obvious when you review the chemical composition of the urea grade 316L types.
