THS-308L/THT-308L (ER308L)

E308L Stainless Steel Welding Wire | Extra-Low Carbon
AWS Classification: AWS A5.9 ER308L
EN Classification: ISO 14343-B-SS308L

Application

  • Shipbuilding
  • Pressure Vessel
  • Energy Industry
  • Heavy Machinery

DETAILS

THS-308L/THT-308L (ER308L) is a 21%Cr-10%Ni extra-low carbon austenitic stainless steel welding wire. Featuring low carbon content, it offers excellent crack and corrosion resistance alongside outstanding all-position welding usability.

Features

  • 21%Cr-10%Ni extra-low carbon austenitic stainless steel formulation
  • Low carbon content resists intergranular carbide precipitation and enhances corrosion resistance
  • Superior crack resistance and high weld metal toughness
  • Excellent all-position welding performance with a stable arc and minimal spatter

Typical Applications

  • Pressure vessels, boilers, and high-pressure storage tanks
  • Chemical, petrochemical, and fertilizer processing equipment
  • Food, beverage, dairy, and pharmaceutical machinery fabrication
  • Cryogenic equipment and low-temperature piping systems

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-308L, and pure Ar for THT-308L.
