1. EQUIVALENT STANDARD AND CONFORMITY
- TIG ER-309L soldering iron has a low carbon content, which reduces its ability to amplify carbide between particles. This increases intergranular corrosion resistance without the use of stabilizers such as columbium (niobium) or titanium.
- TIG ER-309L welding rod has an average manganese content, sulfur impurities, and extremely small phosphorus to create a weld with high strength and long ductility. Especially with a high chromium and nickel content, the weld metal system has very high rust resistance, corrosion resistance, and mechanical indicators.
ER308L is suitable for welding stainless austenitic steels such as A302, A304, A305, A308, and A308L, which need good mechanical quality, durability, and high toughness.
- ER-309L is suitable for welding liners for critical bonding of stainless steel structures.
- ER-309L is welded by semi-automatic technology with 100% Argon or 100% Helium shielding gas (TIG welding) to create a stable weld with little splash and a bright, smooth weld. TIG welding rod ER-309L is suitable for welding all kinds of vessels, including chemical tanks, load-bearing structures, acid-resistant equipment, and equipment in the medical and food industries.
