Exaton 25.22.2.LMn is a manganese alloyed chromium-nickel-molybdenum filler material used for welding Sandvik 2RE69 (UNS S31050, 1.4466), Sandvik 3R60 U.G. (UNS S31603, 1.4435). The weld deposit has excellent low temperature toughness that makes it suitable for joining stainless steels for cryogenic service. It is used for MIG/MAG welding.Exaton 25.22.2.LMn has extensively been used successfully in all critical high-pressure units of modern urea processes, such as:Stripper tubes — Stamicarbon, Montedison IDROuterlayer of bimetallic ( stripper tubes) — SaipemFerrules — All processesCarbamate condensers — All processesDecomposers — MontedisonReactor coils — UTIExaton 25.22.2.LMn has also found extensive use in other corrosive environments in fertilizer plants, such as:– Nitric acid cooler/condensers cooled with polluted cooling water– Heating coils and pipe in NPK plants – Norsk Hydro process
