GM 309L

EXTRA LOW CARBON AUSTENITIC STAINLESS STEEL FILLER ROD.

IDENTIFICATION
GM 309L, ER 309L

CLASSIFICATION
AWS A 5.9: ER309L, BS2901-90309S92,
DIN 8556-86 WSGX2CrNi 24.12

DESCRIPTION
Solid wire deposits a 24 % Cr / 13 % Ni austenitic stainless steel weld metal with a ferrite content about FN 12. The high alloy level and high ferrite content enables the weld metal to tolerate dilution from carbon and low alloy steels without hot cracking. Deposited weld metal is of radiographic quality.
