Equivalent to: GB/T 29713 316L AWS A5.9 ER316L BS EN ISO 14343-A-G 19 12 3 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 shielding gas to be used shall be 98%Ar + 2%CO₂ with a gas flow rate of 15–25 L/min.
2.The welding site must be well sheltered from wind to prevent the dissipation of shielding gas which may cause welding defects.
3.Oil stains, moisture and other contaminants on the welding area must be completely removed.
4.When performing non-consumable electrode filler wire welding processes such as TIG, plasma arc welding or laser welding, the shielding gas shall be 99.99%Ar.
