AWS Class E2594-16 is a super duplex stainless steel coated electrode that features around 25% chromium, 9–10% nickel, 4% molybdenum, and a carefully controlled nitrogen content. This well-thought-out composition results in a balanced duplex microstructure, providing exceptional tensile and yield strength along with remarkable toughness. The weld metal shows outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in environments rich in chlorides, all while ensuring stable arc performance and easy slag removal.
