ER316L is alow-carbon stainless steel welding filler wire (TIG/MIG) containing 18% Chromium, 12% Nickel, and 2% Molybdenum, prized for its superior resistance to pitting and intergranular corrosion, especially in marine, chemical, and food processing environments, due to its low carbon content (max 0.03%) and molybdenum, offering excellent weldability, crack resistance, and performance in cryogenic applications.
Key Characteristics
- Composition: 18% Cr, 12% Ni, 2% Mo, Low Carbon
- and chemical settings.
- Low Carbon (L):The 'L' signifies low carbon (max 0.03%), preventing carbide precipitation during welding, thus preserving corrosion resistance and improving weldability.
- Formability& Toughness:Good formability, flexibility, and toughness, even at cryogenic temperatures, due to its austenitic structure.
- TIG, High-Heat Applications:Electrical heating elements, furnace components.
- Marine & Chemical Processing:Boat fittings, chemical tanks, pharmaceutical equipment.
- General Purpose:Wire mesh, baskets, electronic components.
Forms & Finishes
- Types:Wire spools, coils, filler wire, wire mesh.
- Finishes:Bright (shiny) or matte.
