Adam Stainless, located in Canberra, Australia, has built a solid reputation as a reliable manufacturer and supplier of top-notch welding consumables, including the AWS Class E309/309H-16 electrodes. They’re well-known for their dedication to quality and durability, ensuring that their welding products meet the rigorous AWS standards. The E309/309H-16 electrodes are crafted to perform exceptionally well in tough conditions, providing dependable welds that resist cracking and corrosion. Catering to a variety of industries throughout Australia, Adam Stainless makes sure that welders have access to materials that enhance weld integrity and longevity.
The AWS Class E309/309H-16 electrodes boast a chemical makeup rich in chromium (around 23%) and nickel (about 13%), making them perfect for welding dissimilar metals and stainless steels while offering impressive heat and corrosion resistance. The “H” variant has a higher carbon content (0.04-0.10%) to boost strength and hardness. With mechanical properties that include tensile strengths close to 75 ksi, these electrodes also maintain good ductility and toughness. They excel in resisting thermal cracking, making them ideal for joining carbon steel to stainless steel.

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.
These electrodes are commonly used in various applications, such as connecting stainless steel to carbon steel in boilers, pressure vessels, and furnace components. They also find their place in chemical plants, petrochemical industries, and power generation, where heat resistance and durability are essential. With stable arc performance and easy slag removal, these electrodes help create strong, crack-resistant welds that can handle demanding service conditions.
