The AWS Class E347-16 electrodes boast a chemical makeup rich in chromium (17-19%), nickel (9-12%), and columbium (niobium), which helps stabilize the weld metal and prevents carbide precipitation. This results in welds that have impressive tensile strength—typically around 515 MPa (75 ksi)—and outstanding resistance to stress corrosion cracking. The electrodes are known for their smooth arc characteristics and attractive weld bead appearance, making them suitable for all welding positions.

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.

These electrodes are commonly used for welding stabilized stainless steel components that face high temperatures and corrosive environments, such as boilers, heat exchangers, and pressure vessels. They deliver strong, durable, and corrosion-resistant welds. Thanks to their exceptional performance under thermal cycling and harsh service conditions, AWS Class E347-16 electrodes are a go-to choice for fabrication and repair in demanding industrial settings.
