Exaton 25.22.2.LMn (GTAW)

Exaton 25.22.2.LMn is a manganese alloyed chromium-nickel-molybdenum filler material used for welding UNS S31050, EN 1.4466, (e.g. Alleima® 2RE69). The weld deposit has excellent low temperature toughness that makes it suitable for joining stainless steels for cryogenic service. 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 IDR Outerlayer of bimetallic (stripper tubes) - Saipem Ferrules - All processes Carbamate condensers - All processes Decomposers - Montedison Reactor coils - UTI Exaton 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
