Walid Stainless, based in Tunis, Tunisia, is a leading manufacturer and supplier of high-quality stainless steel products and welding consumables. Renowned for its commitment to excellence, the company specializes in providing durable and reliable welding electrodes, including the AWS Class E309LMo-16. With a focus on precision and stringent quality standards, Walid Stainless serves a diverse clientele across construction, manufacturing, and repair industries. The company emphasizes innovation, consistency, and technical support, ensuring that customers receive products that meet international specifications. Their AWS Class E309LMo-16 electrodes are engineered for superior performance in demanding welding applications.
AWS Class E309LMo-16 electrodes are stainless steel welding rods designed for joining austenitic and dissimilar steels. Their typical chemical composition includes 24–26% chromium, 12–14% nickel, and 0.5–1% molybdenum, providing excellent corrosion resistance and high-temperature strength. These electrodes deliver a tensile strength of approximately 580–690 MPa and exhibit good ductility, toughness, and creep resistance. They produce weld deposits with a smooth finish, minimal cracking, and stable arc characteristics. The inclusion of molybdenum enhances resistance to pitting and stress corrosion cracking in aggressive environments.

These electrodes offer excellent resistance to oxidation and corrosion. They are available in 2.5 mm, 3.2 mm, and 4.0 mm diameters, designed for light-duty applications requiring minimal coating thickness.
These electrodes are known for superior corrosion resistance and are suitable for more demanding conditions. Sizes include 3.2 mm, 4.0 mm, and 5.0 mm, with a thicker coating that enhances durability and performance under heavy-duty usage.
These electrodes provide high resistance to corrosion and oxidation, featuring shielding to protect the weld from atmospheric contamination. Available in 2.5 mm, 3.2 mm, and 4.0 mm diameters, they are ideal for stable arc welding and consistent weld quality.
Our AWS Class E309LMo-16 electrodes are carefully packed in wooden boxes with waterproof protection and lifting points for ease of transport. To ensure full client satisfaction, each order is accompanied by crucial documents such as a commercial invoice, packing list, heat treatment chart and Material Test Certificates, providing full transparency and assurance of product quality.
AWS Class E309LMo-16 electrodes are widely used in welding stainless steels and dissimilar metals, particularly in environments requiring high corrosion and heat resistance. They are ideal for joining 304, 309, and similar stainless steels, as well as overlay applications to protect carbon steel from oxidation and chemical attack. Common industries include chemical processing, power generation, petrochemical, food processing, and shipbuilding. These electrodes are suitable for structural components, pressure vessels, boilers, piping systems, and repair work where durability and resistance to pitting, cracking, and high-temperature corrosion are critical. Their versatility ensures strong, long-lasting welds under demanding conditions.
