SFA-5.9 / AWS A5.9 – ER309LMo
BA-WIRE 309LMo is a submerged arc welding wire similar to BA-WIRE 309L with the addition of 2.0 – 3.5 % molybdenum to increase pitting corrosion resistance. Also used for surfacing of base metals to improve their resistance to corrosion. BA-WIRE 309LMo is suitable for joining stainless steels to carbon steels or low-alloy steels such as 316L to mild steel and for overlay welding where higher Mo content is desired in the second and third layers.
Typiske kjemiske verdier:
• Dissimilar joints between mild steels, low alloy steels, high tensile low alloy steels, ferritic Cr steels, austenitic Cr-Ni steels and manganese steels. Surfacing/overlay for the first layer.
Suitable fluxes: BF 38, WP 380
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.
