Aditya Stainless, a well-respected manufacturer and supplier located in Kolkata, India, specializes in high-quality AWS Class E320LR-16 electrodes, crafted specifically for welding high-alloy austenitic stainless steels. These low-carbon electrodes are engineered to deliver outstanding corrosion resistance and stability, even in harsh chemical and high-temperature settings. With rigorous quality control measures in place, Aditya Stainless guarantees reliable arc performance, minimal carbon absorption, and smooth weld deposits. Their E320LR-16 electrodes are perfect for critical applications that demand both strength and corrosion resistance, establishing Aditya Stainless as a trusted provider of stainless steel welding consumables for challenging industries both in India and internationally.
AWS Class E320LR-16 electrodes from Aditya Stainless feature a carefully controlled blend of chromium (~19-21%), nickel (~33-37%), molybdenum (~2-3%), and a low carbon content to avoid carbide precipitation. The “LR” (Low Residual) label signifies reduced impurities, enhancing both corrosion resistance and mechanical stability. These electrodes boast a tensile strength of around 550–620 MPa (80,000–90,000 psi) and exceptional toughness. The weld metal is resistant to stress corrosion cracking and pitting, particularly in aggressive environments like those involving sulfuric or nitric acid. They also provide a stable arc, a smooth bead appearance, and easy slag removal, ensuring high-quality welds.
