ESAB OK Tigrod 347 TIG Rod

ESAB OK Tigrod 347 is a high-performance stainless steel TIG rod designed for welding stabilized austenitic chromium-nickel alloys, specifically those with 18% Cr and 8% Ni content. It is stabilized with niobium, which enhances resistance to intergranular corrosion, especially in high-temperature environments. This makes it an excellent choice for applications requiring heat resistance and corrosion protection.

Key Features of ESAB OK Tigrod 347

  • Niobium Stabilization: Provides superior resistance to intergranular corrosion and ensures weld durability at high temperatures.
  • Corrosion Resistance: Ideal for applications involving exposure to corrosive environments, such as chemical plants and refineries.
  • High Temperature Applications: Recommended for welding components that operate at elevated temperatures due to its heat-resistant properties.
  • Reliable Mechanical Strength: Offers a tensile strength of 655 MPa and yield strength of 510 MPa, ensuring durable welds.
  • Ferrite Content: Contains approximately 8% ferrite, contributing to excellent weldability and reduced risk of cracking.

Applications

  • Power Generation: Suitable for welding heat exchangers, boilers, and likewise other high-temperature components.
  • Chemical and Petrochemical Industries: Ideal for fabricating and repairing tanks, pipes, and reactors exposed to corrosive chemicals.
  • Food and Beverage Industry: Ensures corrosion-resistant welds for stainless steel equipment used in food processing.
  • General Industrial Fabrication: Suitable for structural components in industries where temperature and corrosion resistance are key.
