What is FCAW E347?

FCAW E347 is a stainless steel flux cored welding wire classified under AWS A5.22 / E347T1 (or equivalent standards depending on shielding system and flux formulation). It is specifically designed for welding stabilized austenitic stainless steels such as 347 and 321 grades.

The key feature of E347 is the addition of columbium (niobium), which stabilizes carbon and prevents carbide precipitation. This improves resistance to intergranular corrosion, especially in high-temperature service conditions. The niobium stabilization also enhances creep resistance and weld durability in elevated temperature environments.

STRONG FCAW E347 is widely used in applications requiring excellent resistance to heat, oxidation, and corrosive environments.
