AWS Class E630-16 electrodes typically contain about 16–17% chromium, 4% nickel, and additives of copper, niobium, and columbium, allowing for precipitation hardening after welding. The weld deposit achieves tensile strengths up to 125,000 psi and yield strengths near 105,000 psi after proper heat treatment, with an elongation of around 15–20%. This mix provides excellent hardness, toughness, and corrosion resistance. The electrodes ensure stable arc performance, minimal spatter, and a good bead appearance, making them reliable for creating strong welds in precipitation-hardening stainless steels like Type 17-4 PH.
