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+
