309LMO STAINLESS STEEL FILLER WIRE

SUPERMIG 309LMo is used for TIG / MIG welding of molybdenum containing high alloy and un-allyoed steels. The presence of molybdeunm improves tensile strength and corrosion resistance. Also suitable for welding of stainless steels type AISI 309 series, 316 type clad steels as well as dissimilar metals such as molybdenum containing austenitic stainless steel to carbon steel etc.

SUPERTIG 309LMo is used for welding of dissimilar steels and also used for buffer layers prior to surfacing, when Mo is a required alloying element.

SUPERTIG 309LMo is used for the welding of stainless steels to mild and medium tensile steels. It is also used for intermediate layers on structural steel prior to depositing 316L grade stainless steel cladding. SUPERTIG 309LMo is suitable for use mainly with Ar shielding gas.

Shield-Bright 309LMo was designed for welding type 316 clad steels on the first pass in cladding steels or for welding dissimilar metals such as molybdenum-containing austenitic stainless steels to carbon steels. It is used in paper mills and in power plants to give greater corrosion resistance. This wire performs best when used out-of-position shielded with either Argon/C02 or 100% C02.

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.

APPLICATIONS

A continuous, solid, corrosion-resistant wire of the ”309LMo” type. 309MoL is used for the overlay welding of unalloyed and low-alloyed steels and for welding dissimilar steels, such as 316L, to unalloyed and low-alloyed steels when Mo is essential.

BASE MATERIAL

• 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.

PROPERTIES

Excelent corrosion resistance against oxidising air upto 950ºC. Good resistance against hot cracking due to the high Mo. content.

SUITABLE FOR

Buffer layers before hard facing, dissimilar joints between ferritic and austenitic steels and or other stainless-steel types to standard carbon steel. Recommended for cladding on low alloyed steel in case AISI 316 is required as first layer.
