Classification:
EN ISO 14343 W 23 12 L
AWS A5.9 ER309 L
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.
