NiMo-alloyed wire electrode with higher Mn-content for submerged arc welding of high tensile pipe steels and high tensile fine grain steels in vessel and apparatus construction as well as Off-Shore applications. Especially suitable for low temperature applications because of low Mo-content. Best suitable if requirements for sour-gas environment are to match Ni < 1,0%.

Flux type suitability is strongly dependent on its application. In combination with the wire electrode the most suitable flux should match the requirements of the plate material as closely as possible under the existing welding conditions. Further information can be obtained from the technical flux data sheets.
