Niazi Stainless is a well-respected manufacturer and supplier based in Manama, Bahrain, known for its top-notch **AWS Class E309/309H-16 Electrodes** that are crafted for high-performance welding in tough industrial settings. The company has built a reputation for creating welding consumables that offer outstanding arc stability, smooth bead formation, and impressive mechanical strength. Their E309/309H-16 electrodes are tailored for high-temperature applications and welding dissimilar metals, ensuring they stand up to wear and resist thermal fatigue. With a wealth of technical know-how, cutting-edge manufacturing processes, and a strong commitment to quality, Niazi Stainless delivers dependable solutions for industries that need robust and corrosion-resistant stainless steel welding electrodes.
AWS Class E309/309H-16 Electrodes feature higher levels of chromium (about 23–25%) and nickel (12–14%), along with a greater carbon content compared to the standard 309 grade. This boost in carbon improves high-temperature strength and creep resistance, making these electrodes perfect for elevated-temperature service. On the mechanical side, they offer high tensile strength, excellent ductility, and reliable toughness. The rutile coating provides smooth arc characteristics, easy slag removal, and less spatter, resulting in clean, strong, and stable welds. This composition is particularly effective for welding stainless steel to carbon steel and other dissimilar metal combinations.

Designed for welding stainless steel to mild steel or other stainless steel types, these electrodes offer high corrosion resistance. Typically available in sizes like 3/32″ to 1/8″ diameter, they provide excellent weld quality with minimal spatter.
These electrodes are ideal for general-purpose welding, offering good corrosion resistance for stainless steel applications. Sizes usually range from 1/8″ to 3/16″ in diameter, and they ensure smooth welding with light flux coatings for improved visibility and control.
Suitable for heavy-duty welding tasks, these electrodes enhance corrosion resistance and are used for thick stainless steel sections. Common sizes include 5/32″ to 1/4″ diameter, featuring a thicker coating for robust and stable arc performance.
We ensure full transparency of our AWS Class E309/309H-16 Electrodes with high-quality assurance. All orders are accompanied by all the necessary documents, such as a commercial invoice, packing list, fumigation certificate, heat treatment chart, and NABL-approved lab test report. We provide Material Test Certificate as per EN 10204/3.1b, PMI Test Certificate, 100% radiography test report, and Third-Party Inspection Certificate. Our comprehensive documentation is organized for maximum client satisfaction.
AWS Class E309/309H-16 Electrodes are commonly used in industries where components face high temperatures, oxidation, and corrosive conditions. They are perfect for welding furnace parts, heat-treatment equipment, boilers, pressure vessels, refinery structures, and petrochemical processing units. These electrodes are also great for dissimilar metal welding, connecting stainless steels to carbon or low-alloy steels, and laying down buffer layers before cladding operations. Their enhanced high-temperature strength and resistance to thermal cycling make them an excellent choice for repairs, ensuring long-lasting performance.
