G 19 12 3 Nb Si
~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+
