~ER309MoL

Description:

Cromamig 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.

Welding current:

DC+

Corrosion resistance

The corrosion resistance after surfacing carbon

steels with two layers of Cromamig 309 MoL is

about the same as for 316L material.
