E309LMo‑16 contains about 22–24% chromium, 12–15% nickel, and adds 2–3% molybdenum to improve resistance to pitting and crevice corrosion. The weld metal achieves a tensile strength of roughly 550–650 MPa and good ductility. Its structure resists grain growth at high temperatures, producing stable welds during cycling heating and cooling. The low carbon content and addition of molybdenum enhance its corrosion resistance in harsh chemical environments.
