Description

The E309LT1-1 is a gas-shielded stainless steel flux-cored wire designed for welding 309/309L stainless steels and dissimilar metals (e.g., carbon steel to austenitic stainless steel). With high chromium-nickel content (Cr 23-25%, Ni 12-14%) and low carbon (C≤0.03%), it delivers exceptional resistance to high-temperature oxidation (≤900℃), corrosion, and cracking. The rutile-based slag system, combined with shielding gas, ensures smooth all-position welding, minimal spatter, and consistent bead appearance.

KEY FEATURES

  • Dissimilar Metal Welding： Optimized for carbon steel-to-stainless steel joints， minimizing carbon migration and dilution.
  • Corrosion Resistance：Resists weak acids (e.g., sulfuric, phosphoric), compliant with chemical industry standards
  • Smooth Arc: Produces a stable, smooth arc that ensures easy handling and high-quality welds.
  • Minimal Spatter: Produces minimal spatter, reducing post-weld cleaning time.
  • Automation Ready: Ideal for robotic systems with stable wire feeding.
  • All position welding
  • Suitable for Petrochemical，Energy，Hybrid Structures，Heat Treatment
  • Shielding gas: 100%CO2 or 75%Ar+CO2
