Khaleed Stainless is a reputable manufacturer and supplier of AWS Class E320LR-16 Electrodes based in Dubai, UAE. They provide top-notch welding consumables tailored for critical industrial applications. These electrodes are specifically crafted for welding alloy 20 stainless steels and similar alloys that demand exceptional resistance to corrosion, especially in harsh environments like sulfuric acid. The “LR” (Low Residual) grade is designed to minimize levels of carbon, silicon, and other residual elements, which significantly enhances resistance to intergranular corrosion and cracking. With E320LR-16, you can expect stable arc performance, smooth weld beads, and hassle-free slag removal.

AWS Class E320LR-16 Electrodes are made with carefully controlled amounts of nickel (33–37%), chromium (19–21%), iron, molybdenum (2–3%), copper (3–4%), manganese, and very low carbon content (<0.03%). This low residual composition not only boosts weld quality but also reduces the risk of hot cracking and carbide precipitation. In terms of mechanical properties, these electrodes offer a tensile strength of about 550–650 MPa, a yield strength of around 300 MPa, and an elongation of 30–35%. These characteristics ensure that the welds are durable and resistant to corrosion, even in challenging chemical processing environments.
