Lecong Stainless Manufacturer and Suppliers in Da Nang, Vietnam, offers high-quality welding electrodes, including AWS Class E309LMo-16. These electrodes are designed for joining stainless steels to carbon steels and for overlay applications. The addition of molybdenum improves resistance to pitting and crevice corrosion in environments with chlorides. Their low-carbon design reduces the risk of carbide precipitation, ensuring durable welds with a long service life. Lecong Stainless guarantees product consistency, reliability, and adherence to international standards. These electrodes are widely used in petrochemical, marine, and chemical processing industries that demand superior corrosion resistance and mechanical strength.
AWS Class E309LMo-16 electrodes contain about 23% chromium, 13% nickel, and 2.5–3% molybdenum, with low carbon content to prevent carbide formation. This composition enhances resistance to pitting and crevice corrosion in harsh chloride conditions. Mechanical properties include tensile strength of around 85,000 psi, yield strength near 60,000 psi, and an elongation of about 30%. The weld deposit shows excellent strength, toughness, and corrosion resistance at high temperatures. With stable arc performance, a smooth bead appearance, and reliable crack resistance, E309LMo-16 ensures strong, durable welds in demanding industrial applications.
