About ER430LNB Tig Wire

ER430LNB TIG wire is a low-carbon stainless steel filler metal with niobium added for stabilizing welds. It provides excellent corrosion resistance and weldability, making it suitable for welding ferritic stainless steels in applications such as automotive exhaust systems, kitchen equipment, and architectural structures.

ER430LNB Tig Wire Chemical Compositions:

  1. Chromium (Cr):0-18.0%
    • Chromium content contributes to corrosion resistance by forming a protective oxide layer on the surface of the weld.
  2. Nickel (Ni): ≤ 0.75%
    • Nickel enhances the wire’s ductility and toughness, improving weldability and resistance to corrosion.
  3. Manganese (Mn): ≤ 1.0%
    • Manganese aids in deoxidation, ensuring a clean weld pool and minimizing the formation of unwanted oxides.
  4. Silicon (Si): ≤ 1.0%
    • Silicon improves the fluidity of the weld pool and promotes better penetration, resulting in strong, uniform welds.
  5. Carbon (C): ≤ 0.03%
    • Low carbon content minimizes carbide precipitation, reducing the risk of intergranular corrosion and improving weld strength.
  6. Niobium (Nb):30-0.60%
    • Niobium stabilizes the welds against sensitization and intergranular corrosion, ensuring long-term durability.
  7. Phosphorus (P): ≤ 0.04%
    • Phosphorus content is minimized to avoid embrittlement of the weld and maintain its mechanical properties.
  8. Sulfur (S): ≤ 0.03%
    • Sulfur content is kept low to prevent hot cracking during welding and ensure sound, defect-free welds.
  9. Iron (Fe): Balance
    • Iron serves as the base element of the alloy, providing structural integrity and stability to the wire.
