What is AWS Class E309/309H-16 Coated Electrodes?
The AWS Class E309/309H-16 Coated Electrodes are made from austenitic stainless steel, enriched with chromium, nickel, and a controlled amount of carbon. The 309H grade stands out with its higher carbon content, which enhances its strength at elevated temperatures. The coating on these electrodes guarantees stable arc characteristics, easy slag removal, and a smooth bead finish. The weld metal produced is known for its impressive tensile and yield strength, excellent ductility, and high toughness, along with a strong resistance to hot cracking and thermal stress. These features make the electrodes ideal for welding stainless steels and various steel combinations, even under challenging conditions.
