Description
ER347 is stabilized by Nb austenitic stainless steel type material used for welding of Ti and Nb stabilized CrNi steels (like 321 and 347).
Is characterized by high resistance to intergranular corrosion and oxidizing environments. Weld metal is suitable for operating temperatures of up to +400°C, non-scaling up to +800°C , in air and oxidizing combustion gases.
General areas of application: food, beverage, chemical and petrochemical industries.
