Ed Stainless offers AWS Class E347-16 Electrodes, ideal for welding stainless steels with a higher carbon content. The electrodes are designed to produce robust, crack-proof welds with high intergranular corrosion and thermal fatigue resistance. Suitable for high-temperature applications, the E347-16 electrodes ensure that carbide precipitation does not occur at high temperatures, maintaining the strength of the weld. Mostly employed in the construction of pressure vessels, boilers, and heat exchangers, these electrodes become the industry’s first choice where high performance and hardness are the core requirements.
AWS Class E347-16 Electrodes contain stainless steel with the composition 19-22% Chromium, 9-12% Nickel, and trace amounts of Silicon, Manganese, and Carbon. The electrodes are particularly used for welding high-carbon stainless steels like 347 and 321 grades. They possess greater intergranular corrosion resistance and high-temperature strength. The tensile strength of these electrodes is approximately 600 MPa, with their yield strength around 250 MPa. Their carbide precipitation resistance under heat conditions makes them suitable for welding process involving high-temperature stability and corrosion resistance.

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.
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.
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.

AWS Class E347-16 Electrodes are widely employed in processes involving welding high carbon content stainless steels like 347 and 321 grades. The electrodes are well suited for welding in high-temperature conditions where resistance to intergranular corrosion is essential. The typical uses are pressure vessels, heat exchangers, boilers, and chemical equipment that operate in high-temperature settings. Also, they are often used in aerospace, nuclear, and petrochemical applications, where materials are subjected to extreme thermal stresses. Their resistance to carbide precipitation makes them ideal for application in welded joints to be exposed to high temperatures and abusive environments.
