Vinit Stainless is a top-class manufacturer and exporter of AWS Class E309LMo-16 Electrodes in Chennai, India, providing high-performance welding solutions for corrosive and high temperature service. The electrodes are for the joining of dissimilar metals and for service where resistance to aggressive corrosion, especially in chloride– or acid-containing media, is needed. Molybdenum addition provides improved pitting and crevice corrosion resistance. Vinit Stainless delivers consistent product quality, good arc characteristics, and low spatter. Their E309LMo-16 electrodes are employed in chemical processing, offshore platforms, and petrochemical equipment, where metallurgical stability and toughness are essential for sustained service performance during thermal or chemical stress.
E309LMo-16 Electrodes have 22–24% chromium, 12–14% nickel, 2–3% molybdenum, and ≤0.04% carbon. Intergranular corrosion is minimized by the low carbon content and molybdenum improves resistance to chlorides and reducing acids. Fully austenitic weld metal deposited, it is stable at high temperature. Mechanical properties are tensile strength 580–600 MPa, yield strength approximately 420 MPa, and elongation 30%. These electrodes provide excellent hot cracking resistance and can be used for high-strength and corrosion-resistant joints in welds, especially in harsh chemical environments or where joining dissimilar metals is required.

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.
AWS E309LMo-16 Electrodes are applied in welding dissimilar metals and for buffer layers where there is a need for improved corrosion resistance. They find extensive use in chemical plants, desalination facilities, and offshore oil platforms where chloride-induced pitting resistance is of great importance. The electrodes are applicable in welding stainless steels to carbon or low-alloy steels and particularly in sulfuric acid or saltwater conditions. E309LMo-16 finds applications in heat exchangers, pressure vessels, and piping that need both corrosion resistance and structural strength. Molybdenum addition assures longer service life even under rigorous chemical and heat exposure.
