ED035015 - Lincoln Excalibur 410NiMo-16 Stainless Stick Electrode 1/8"

Premium Martensitic Stainless Steel Electrode

The Lincoln Electric Excalibur 410NiMo-16 is a high-performance stick electrode designed specifically for welding materials of similar chemical composition, such as ASTM CA6NM castings and 410 stainless steel. This electrode is engineered to deposit a martensitic stainless steel weld metal that contains nominal additions of nickel and molybdenum. These alloying elements significantly improve the toughness and ductility of the weld deposit compared to standard 410 grades, making it an excellent choice for critical industrial applications where mechanical integrity is paramount.

Part of the renowned Excalibur family, this electrode features a proprietary coating formulation that delivers superior moisture resistance. This is critical for preventing hydrogen-induced cracking, a common challenge when welding hardenable martensitic steels. The coating also ensures a smooth, stable arc with minimal spatter, allowing for precise control during the welding process. The slag system is designed to be self-releasing in many instances, or easily removable, which reduces cleanup time and improves overall productivity in fabrication and repair environments.

The E410NiMo-16 is particularly well-suited for surfacing and overlay applications on mild and low-alloy steels, providing a durable, corrosion-resistant surface. It is widely utilized in the power generation sector, specifically for the fabrication and repair of hydroelectric turbine runners, valve bodies, and pumps where resistance to cavitation, erosion, and corrosion is required. To ensure optimal results, preheat and interpass temperatures should be carefully managed (typically above 300°F), and post-weld heat treatment is recommended to temper the martensitic structure without exceeding the critical transformation temperature.
