Walid Stainless, located in Tunis, Tunisia, has earned a solid reputation as a reliable manufacturer and supplier of top-notch welding consumables tailored for industrial use. One of their standout products is the AWS Class E320LR-16 electrodes, specifically crafted for welding low-alloy steels that demand high toughness and outstanding mechanical properties. These electrodes deliver smooth arc performance, stable metal transfer, and robust, crack-resistant weld deposits. With a commitment to advanced manufacturing techniques and rigorous quality control, Walid Stainless ensures consistent performance across various sectors, including power generation, construction, pressure vessel fabrication, and heavy engineering, where durability, strength, and reliability are crucial.
The AWS Class E320LR-16 electrodes are primarily made of iron, with carefully controlled amounts of manganese, chromium, molybdenum, and nickel added to boost strength and toughness. The resulting weld metal achieves impressive tensile strength, typically ranging from 80 to 90 ksi (550 to 620 MPa), along with good elongation and impact resistance. This thoughtful composition guarantees uniform mechanical properties, reduces the risk of cracking, and ensures excellent performance even in high-stress situations.
