AWS Class E347-16 electrodes deposit a niobium-stabilized austenitic stainless steel weld metal containing chromium and nickel. The addition of niobium (columbium) helps prevent carbide precipitation at high temperatures, improving resistance to intergranular corrosion. The weld metal offers good tensile strength, excellent ductility, and high toughness. These electrodes provide stable arc characteristics with AC or DC current, smooth slag removal, and reliable mechanical performance in both ambient and elevated temperature service.

Types of AWS Class E347-16 Electrodes

Stainless Steel AWS Class E347-16 Light Coated Electrodes

These electrodes offer exceptional corrosion resistance, particularly against intergranular corrosion. Typically available in diameters of 1/16″ to 1/8″ (1.6 mm to 3.2 mm), they provide a lighter coating, facilitating easier welding with smooth, clean welds and minimal spatter.

Stainless Steel AWS Class E347-16 Heavy Coated Electrodes

Known for high corrosion resistance, especially in harsh environments, these electrodes come in diameters of 1/8″ to 5/32″ (3.2 mm to 4.0 mm). The heavy coating enhances arc stability and provides a thicker slag layer, offering better protection and ease of removal for cleaner welds.

Stainless Steel AWS Class E347-16 Shielded Arc Electrodes

These electrodes deliver superior corrosion resistance and are ideal for high-temperature applications. Typically available in diameters of 3/32″ to 1/8″ (2.4 mm to 3.2 mm), they are designed for shielded arc welding, ensuring stable arcs and good weld integrity in challenging conditions.

We guarantee complete transparency and top-notch quality assurance for our AWS Class E347-16 Electrodes. All orders are accompanied by necessary documents such as a commercial invoice, packing list, fumigation certificate, heat treatment chart, and an NABL-approved lab test report. We also provide a Material Test Certificate as per EN 10204/3.1b, PMI Test Certificate, 100% radiography test report, and Third-Party Inspection Certificate. Our documentation is very well arranged to ensure the highest level of client satisfaction.
