What is AWS Class ER316LMN Welding Wire?
AWS Class ER316LMN is a low-carbon austenitic stainless steel welding wire that includes chromium, nickel, molybdenum, and nitrogen in its composition. Typically, it contains around 18–20% chromium, 11–14% nickel, 2–3% molybdenum, along with a controlled amount of nitrogen. This unique blend boosts both tensile and yield strength while ensuring excellent ductility and toughness. The weld metal produced offers enhanced resistance to pitting and crevice corrosion, stable arc characteristics, and dependable mechanical properties even in harsh service conditions.
