AWS A5.9 ~ER309LMo
Description:
Cromatig 309MoL deposits a 23% Cr / 12% Ni / 2.5% Mo austenitic stainless steel weld metal. The
high alloy content and ferrite level enable the weld metal to tolerate dilution from dissimilar and
difficult-to-weld materials without hot cracking.
APPLICATIONS:
– Buffer layers on mild and low alloy steels prior to overlaying with Cromarod 316L.
– Joining of 316L clad steels and dissimilar joints between stainless and mild or medium carbon
steels.
– Joining of medium carbon hardenable steels.

Corrosion resistance
The corrosion resistance after surfacing carbon
steels with two layers of Cromatig 309 MoL is
about the same as for 316L material.
