Composition: ER347 wire is a chromium-nickel (Cr-Ni) stabilized austenitic stainless steel.
The addition of niobium (Cb/Nb) acts as a stabilizer, binding with carbon to form niobium carbides instead of chromium carbides.
This stabilization greatly enhances the wire’s resistance to intergranular corrosion, especially in conditions where the material is exposed to higher temperatures.
Weldability: It offers good weldability and is known for producing high-quality, radiographic weld deposits.
ER347 wire is used to weld base metals of similar composition (321 and 347 grades) in industries that demand durability and resilience at elevated temperatures.
