Why Choose ER347?
Stabilized Stainless Weld Metal
ER347 contains columbium, also known as niobium, which stabilizes the alloy and helps improve resistance to intergranular corrosion in compatible stainless steel applications.
Designed for 347 & 321 Stainless
ER347 is commonly selected when welding Type 347, Type 321 and other compatible stabilized stainless steels requiring similar weld-metal chemistry.
Product Selection Considerations
Wire Diameter
Select .035" or .045" wire based on material thickness, welding parameters, deposition requirements, equipment capability and the applicable welding procedure.
Base-Metal Compatibility
Confirm ER347 filler-metal compatibility with the stainless alloys being joined, service temperature, corrosion environment and applicable welding specification before use.
