What is AWS Class ER308/308H SAW & Flux?
The AWS Class ER308/308H SAW wire is an austenitic stainless steel filler metal that boasts a balanced mix of chromium and nickel. The 308H grade, in particular, has a higher carbon content, enhancing its strength at elevated temperatures. When paired with the right flux, this system offers stable arc characteristics, easy slag removal, and clean weld beads. The weld metal produced shows impressive tensile and yield strength, excellent toughness, and dependable ductility. These mechanical properties help prevent hot cracking, ensure sound weld integrity, and maintain stable performance in both regular and high-temperature conditions.
