Amer Stainless in Amman, Jordan supplies reliable AWS Class E309/309H-16 welding electrodes designed for joining stainless steel to carbon steel and for surfacing applications requiring strong corrosion and heat resistance. Known for smooth arc performance, consistent quality, and easy slag removal, these electrodes meet rigorous international standards. Amer Stainless provides dependable welding solutions for fabricators, maintenance teams, and industrial plants, ensuring durable and clean welds across a variety of operating conditions. Their E309/309H-16 electrodes are trusted for both structural fabrication and high-temperature service applications.
AWS Class E309/309H-16 electrodes contain high levels of chromium and nickel, giving them excellent resistance to oxidation, heat, and corrosion. The “H” grade includes a controlled higher carbon content, enhancing creep strength and stability at elevated temperatures. These electrodes offer strong mechanical properties, including high tensile strength, good ductility, and reliable toughness under thermal cycling. Their rutile coating ensures smooth arc stability, minimal spatter, and easy slag detachment, allowing welders to produce consistent, high-quality welds even on challenging material 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.
E309/309H-16 electrodes are widely used for welding dissimilar metals, particularly stainless steel to carbon steel or low-alloy steel. They are also used for buffer layers before applying more corrosion-resistant overlays and for build-up work on worn or damaged components. Common applications include boilers, heat exchangers, furnace parts, pressure vessels, chemical processing lines, and industrial piping systems. Their strong heat and oxidation resistance make them suitable for high-temperature environments, while their versatility and reliability support both fabrication and maintenance operations across multiple industrial sectors.
