309LMo

Category

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.
