Types of AWS Class E320LR-16 Electrodes

Stainless Steel AWS Class E320LR-16 Light Coated Electrodes

Excellent corrosion resistance and are suitable for welding stainless steel structures. They come in various diameters, such as 2.5 mm, 3.2 mm, and 4.0 mm. The light coating facilitates smooth arc stability and minimal spatter.

Stainless Steel AWS Class E320LR-16 Heavy Coated Electrodes

Superior corrosion resistance, heavy-coated electrodes are ideal for high-stress applications. They are available in diameters of 3.2 mm, 4.0 mm, and 5.0 mm. The heavy coating enhances the weld’s integrity and improves its resistance to oxidation.

Stainless Steel AWS Class E320LR-16 Shielded Arc Electrodes

Excellent corrosion resistance, these electrodes are designed for shielded arc welding of stainless steel. They are typically available in 2.5 mm, 3.2 mm, and 4.0 mm. The shielded arc provides enhanced protection against contamination during welding.

They are best suited for welding 320LR stainless steel parts, such as heat exchangers, storage tanks, and piping systems that are exposed to highly corrosive media. These electrodes have superior resistance to sulfuric and other acidic environments and are thus well-suited for chemical plants. They are also employed in food processing and production of medical equipment, where even higher corrosion resistance and mechanical strength are required.
