Harshita Stainless, a well-respected manufacturer and supplier located in Delhi, India, focuses on providing top-notch welding solutions, including the AWS Class E320LR-16 Electrodes. These electrodes are specifically designed for welding alloys that share similar chemical properties, particularly in situations where corrosion resistance and strength are crucial in harsh environments. Harshita Stainless is dedicated to delivering products that adhere to global standards, ensuring consistency, performance, and reliability. The E320LR-16 electrodes feature a lower carbon content to minimize the risk of intergranular corrosion, making them perfect for applications involving aggressive chemicals and thermal cycling, which are common in the chemical processing, pharmaceutical, and marine sectors.
AWS Class E320LR-16 Electrodes are mainly made up of Chromium (19–21%), Nickel (32–36%), Molybdenum (2–3%), and a low Carbon content (maximum 0.03%) to enhance corrosion resistance. This electrode offers outstanding weld metal toughness and effectively resists hot cracking. The weld metal typically achieves tensile strengths around 620 MPa, yield strength of about 400 MPa, and an elongation of roughly 30%. The low-carbon formulation helps reduce carbide precipitation during welding, boosting resistance to intergranular attack. These electrodes provide smooth arc stability, easy slag removal, and are suitable for AC or DC+ welding in any position.
