63181600 - Bonarc ER316L Stainless Steel TIG Rod 1.6mm - 5kg Tube

Professional Grade ER316L TIG Filler Metal

Elevate your stainless steel fabrication with the Bonarc ER316L TIG Welding Rod. This 1.6mm diameter filler metal is formulated for the Gas Tungsten Arc Welding (GTAW) process, specifically targeting the welding of molybdenum-bearing austenitic stainless steels like Type 316 and 316L. Supplied in a 5kg protective tube, these rods are an essential consumable for professional welders working in industries where corrosion resistance is paramount, such as petrochemical, textile, and pulp and paper industries.

The primary advantage of the ER316L alloy over standard 308L is its superior resistance to creep and corrosion at elevated temperatures. The inclusion of Molybdenum creates a robust microstructure that withstands harsh chemical environments, including sulfuric acid and chlorides. Furthermore, the extra-low carbon content (maximum 0.03%) effectively prevents intergranular corrosion (sensitization), eliminating the need for post-weld annealing in many applications. This makes it a highly efficient choice for multi-pass welding on heavy sections or critical pipe work.

Technical Excellence and Usability

Bonarc's manufacturing process ensures that each rod is clean, straight, and free from surface contaminants that could introduce porosity into the weld pool. The 1.6mm size is versatile, allowing for fine control on root passes or precise fillet welds on thinner sheet metal. Welders will appreciate the smooth flow and excellent wetting characteristics, which help in producing concave bead profiles that blend seamlessly with the base material.

Recommended Operating Parameters:

• Current: DCEN (Direct Current Electrode Negative)
• Shielding Gas: 100% Argon
• Tungsten: 2% Thoriated, Ceriated, or Lanthanated

Whether you are fabricating pressure vessels or sanitary piping systems, the Bonarc ER316L provides the metallurgical assurance needed for high-stakes welding. It is also compatible for use on 304 series stainless steels when higher corrosion resistance is desired, although 308L is the standard for that grade.
