THS-316L/THT-316L (ER316L)
ER316L Stainless Steel Welding Wire | Acid Resistant
Application
- Shipbuilding
- Pressure Vessel
- Energy Industry
- Heavy Machinery
DETAILS
THS-316L/THT-316L (ER316L) is a 19%Cr-12%Ni-2%Mo stainless steel welding wire. Containing molybdenum, it offers excellent corrosion resistance against acetic, sulfurous, and phosphoric acids as well as salts, alongside outstanding all-position welding usability.
Features
- 19%Cr-12%Ni-2%Mo extra-low carbon austenitic stainless steel formulation
- Molybdenum addition significantly increases resistance to pitting and crevice corrosion
- Exceptional protection against organic and mineral acids (acetic, sulfurous, phosphoric) and marine salts
- Smooth, stable arc performance with minimal spatter and clean weld bead appearance
Typical Applications
- Chemical, petrochemical, and synthetic fiber processing equipment
- Pharmaceutical, food, beverage, and dairy machinery fabrication
- Marine structures, coastal installations, and seawater-exposed components
- Pulp, paper, and textile dyeing industry equipment
Welding Positions
- PA / PB / PC / PD / PE / PF
WARNING
- Rust, oil, moisture, and other contaminants must be removed from the weld zone before welding.
- Shielding gas: Ar + (1%–3%) O₂ is recommended for THS-316L, and pure Ar for THT-316L.
