25.22.2.LMn
25.22.2.LMn is a manganese alloyed chromium-nickel-molybdenum filler material used for welding UNS S31050, 1.4466 or UNS S31603, 1.4435. The weld deposit has excellent low temperature toughness that makes it suitable for joining stainless steels for cryogenic service. 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 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 It is used for TIG-welding.

Ok 48.00
A reliable, general purpose electrode for manual metal arc welding of carbon steels, carbon manganese steels and fine-grained carbon manganese steels with elevated yield strength. OK 48.00 deposits a tough, crack-resistant weld metal. The coating is of the low moisture absorption type. High welding speed in the vertical-up position. OK 48.00 is insensitive to the composition of the base material within fairly wide limits. The electrode can be used for welding structures where difficult stress conditions cannot be avoided. Tested according to NACE TM0177 and TM0284. Diffusible Hydrogen tested in various conditions show values below 3 ml/100g.
