Aditya Stainless, a well-respected name in the world of welding consumables located in Kolkata, India, proudly offers top-notch AWS Class E308/308H-16 Electrodes designed for manual arc welding of austenitic stainless steels. These electrodes are expertly crafted for welding 304 and 304H stainless steels, along with similar grades. The E308/308H-16 combines the impressive corrosion resistance of ER308 with the added benefit of higher carbon content from 308H, making it perfect for high-temperature applications. With a rutile coating, these electrodes ensure stable arc performance, easy slag removal, and smooth weld beads. Aditya Stainless is committed to delivering consistent quality and performance, catering to the needs of construction, chemical processing, pressure vessels, and general fabrication industries.
E308/308H-16 electrodes are made up of about 18–21% chromium, 9–11% nickel, and a carbon content ranging from 0.04–0.08% (which is higher than standard 308 for enhanced high-temperature strength). These electrodes typically achieve a tensile strength of ≥ 80,000 psi (550 MPa), a yield strength of ≥ 55,000 psi (380 MPa), and an elongation of around 30%. The weld metal is known for its good oxidation resistance and toughness even at elevated temperatures. The “16” designation signifies that these electrodes can be used with both AC and DC current, producing a smooth, spray-like arc with minimal spatter. The higher carbon variant (308H) boosts creep resistance, making it ideal for high-heat service conditions.
