Aug 26, 2019 · Sandvik 3R60™ Urea Grade is a high purity variant of ASTM 316L, specially developed for the urea industry. The grade has a guaranteed maximum ferrite content of 0.6%. Sandvik 3R60™ Urea Grade is characterized byHigh resistance to corrosion in ammonium carbamate. High resistance to intergranular corrosion.
The UREA 316L Modified grade can be welded with most of the welding processesTIG, 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

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.
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
UREA 316L Modified grade has been specially developed for Urea plant applications. It is a 316L modified stainless steel with extra low silicon content and substantial higher molybdenum contents. The low carbon content, combined with a well balanced chemistry (low silicon and nickel content close to 14%) makes the alloy fully austenitic, free of intermetallic phase precipitations.
Stainless Steel. Choose S31803/S32205 and 316L (Urea Grade) be the trial grade, compare each property of duplex stainless steel and austenitic stainless steel. So as to, based on acquaintance of 316L steel, deepen understanding of mechanical properties and corrosion properties of duplex steel.
Aug 22, 2013 · 316L in strippers The wall temperature in a stripper is far too high for even a Urea Grade 316L type, the firs strippers had 316LUG tubes and the tubes lasted only a few months. This material is absolutely inadequate for stripper tubes, liner overlay welds and internals can be made in a Urea Grade 316L but then with the addition of sufficient oxygen.

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
Earlier, SS 316L UG (urea grade) was used with high amount of oxygen supply. Recent trend for selection of MOC involves application of 25Cr 22Ni 2Mo, Safurex, DP 28W, depending on the process licensors, in HP section. Equipment such as Urea reactor, Urea stripper, Carbonate condenser, Carbonate ejector are constructed with
(316L) and corresponding grades used in the production of urea, nitric acid, sulphuric acid, acetic acid and in gas treat ment plants. The weld deposit has excellent low tempera ture toughness that makes it suitable for joining stainless steels for cryogenic service. ChEMiCaL CoMpoSiTioN Filler metal Chemical composition, wt%
The 310MoLN steel grade has an optimized chemical composition designed specifically for applications in urea plants. The nitrogen in the chemical composition helps to stabilize and strengthen the austenitic phase. This material provides improved corrosion resistance in urea carbamate environments such as high pressure strippers.

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 .
elevated temperature. In addition to excellent corrosion resistance and strength properties, the Types 316, 316L, 317, and 317L Cr Ni Mo alloys also provide the excellent fabricability and formability which are typical of the austenitic stainless steels. Specifications. Chemical Composition, % 18.
