Classification:
EN ISO 14343 G 19 12 3 Nb Si
AWS A5.9 ~ER318
Description:
Cromamig 318Si is designed for welding the Nb or Ti stabilised 18% Cr/12% Ni/3% Mo austenitic
stainless steel grades 316 Cb and 316Ti. It is primarily intended for use at service temperatures
above 400°C, but for structural applications at elevated temperatures the creep strength of the weld
metal should always be considered.
Welding current:
DC+
Shielding gas:
M12, Ar + 2% CO2, 16-21 l/min
M13, Ar + 1-3% O2, 16-21 l/min
Wire composition, wt.%
