Description:

Cromatig 309L deposits a 24% Cr / 13% Ni austenitic stainless steel weld metal with a ferrite content

of about FN 11. The high alloy level and high ferrite content enables the weld metal to tolerate dilution

from carbon and low alloy steels without hot cracking.

APPLICATIONS:

– Buffer layers on mild and low alloy steels prior to overlaying with MIG/TIG 308L.

– Joining of clad steels and dissimilar joints between stainless and mild or low alloy steels.

– Welding of similar composition, 309L type, stainless steels.

– Joining of ferritic-martensitic stainless steels.

Corrosion resistance

As Cromatig 309 L is usually used for buffer layers

and dissimilar joints, corrosion resistance is of

less importance. Two layers on mild steel is about

equivalent to 304L type material.
