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