Applications

CEWELD® 309LMo Tig is a solid, corrosion-resistant '309LMo' type wire used for overlay welding unalloyed and low-alloy steels, as well as dissimilar steels such as 316L to unalloyed and low-alloy steels, where molybdenum (Mo) is essential. It is also used for buffer layers before hard facing and for dissimilar joints between ferritic and austenitic steels, as well as for joining other stainless steel types to standard carbon steel. It is recommended for cladding on low-alloyed steel when AISI 316 is required as the initial layer.

Properties

CEWELD® 309LMo Tig has excellent corrosion resistance in oxidising air up to 950°C. It has good resistance to hot cracking due to its high molybdenum content. During build-up welding, the weld metal achieves the composition of ASTM 316 in the first layer.
