Classification:
EN ISO 14343 G 19 13 4 L
AWS A5.9 ER317L
Description:
Cromamig 317L is intended for welding the 19% Cr / 13% Ni / 3.5% Mo, type 317L, austenitic
stainless steels. The higher Mo content provides better resistance to both acid and pitting corrosion,
compared to grade 316L material. The wire is also recommended for welding 316L and 316LN grades
when it is necessary to ensure enhanced Mo level in the weld metal.
Welding current:
DC+
Shielding gas:
M12, Ar + 2% CO2, 16-21 l/min
M13, Ar + 1-3% O2, 16-21 l/min
