The ER316LSi filler metal contains 18–20% chromium, 11–14% nickel, 2–3% molybdenum, ≤0.03% carbon, and a high silicon content of 0.65–1.0%. This mix guarantees excellent resistance to pitting, crevice corrosion, and intergranular attack. With a tensile strength of at least 75 ksi and a yield strength of 57 ksi, it maintains an elongation of 30% or more. The added silicon improves arc stability, creates smooth fluid weld beads, and reduces spatter. These mechanical properties ensure reliable joint strength and fatigue resistance, making it ideal for tough service conditions.
