Equivalent to: GB/T 17854 309L AWS A5.9 ER309L BS EN ISO 14343-A-S 23 12 L
Characteristics and Applications
The weld metal is of the 22Cr-12Ni grade with an austenitic structure, featuring excellent crack resistance and weldability. It is suitable for welding low-carbon stainless steel, low-carbon cladded steel, 309S, heat-resistant 13Cr steel as well as dissimilar metals.
Precautions
1.The flux must be baked at 350℃ and held at that temperature for 1 hour before use. Ensure it is kept dry to prevent porosity.
2.Welding with high heat input is feasible.
3.When reusing the flux, mix it with an appropriate amount of new flux to guarantee favorable welding quality.
