309LMo

Category 
GMAW-GTAW Solid wires
type 
Solid stainless steel wire for dissimilar welding and cladding.
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.
Properties 

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