Equivalent to: GB/T 29713 308L AWS A5.9 ER308L BS EN ISO 14343-A-G 19 9 L
Characteristics & Applications
The weld metal is of 19Cr-9Ni austenitic structure. It is suitable for welding materials such as 18Cr-9Ni (304, 304L), 301 and 302. It features excellent weldability, along with good heat and corrosion resistance.
Precautions
1.The shielding gas to be used shall be 98%Ar + 2%CO₂ with a flow rate of 15–25 L/min.
2.The welding site must be properly wind-shielded 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 thoroughly cleaned.
4.For non-consumable electrode filler wire welding processes such as TIG, plasma arc welding and laser welding, the shielding gas shall be 99.99% high-purity argon.
