Khaleed Stainless stands out as a leading manufacturer and supplier of AWS Class E309LMo-16 Electrodes in Riyadh, Saudi Arabia. They provide top-notch welding consumables specifically designed for stainless steel and dissimilar metal applications. These electrodes are infused with molybdenum, which significantly boosts their resistance to pitting and crevice corrosion, making them perfect for use in harsh chemical and marine environments. With features like smooth arc stability, easy slag removal, and an impressive weld bead appearance, they ensure dependable performance whether you’re fabricating or repairing.
Typically, AWS Class E309LMo-16 Electrodes are made up of chromium (22–24%), nickel (12–14%), molybdenum (2–3%), and a low carbon content (≤0.04%). The addition of molybdenum enhances their resistance to chlorides and acidic conditions, while the low carbon content helps reduce carbide precipitation. In terms of mechanical properties, these electrodes boast a tensile strength of around 550–650 MPa, a yield strength of about 300 MPa, and a minimum elongation of 30%. They create tough and stable weld deposits that are highly resistant to cracking and corrosion, even in tough 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 primarily used for welding stainless steels, particularly in applications requiring high strength, corrosion resistance and toughness. These electrodes are well suited for joining 309 and similar grade stainless steels. They have good weldability and low heat input. They are used in industries such as chemical processing, petrochemical, power generation, and food processing. The addition of molybdenum enhances resistance to pitting, crevice corrosion, and stress corrosion cracking, making them ideal for harsh environments.
