Weston Stainless, which is headquartered in Midland, UK, is a top distributor of high-quality stainless steel products to industries including construction, manufacturing, and energy. One of its specialty welding consumables is the AWS Class E309/309H-16 Electrodes, which are suitable for high-temperature and corrosion-resistant use. These electrodes, which come in stick or rod form, consist of austenitic stainless steel with a higher carbon content, providing better strength and heat resistance. Graded at E309/309H-16, they are best suited for welding dissimilar steels, stainless to carbon steel, and applications involving higher oxidation and heat resistance.
The AWS Class E309/309H-16 Electrodes have a chemical makeup consisting of Chromium (23-25%), Nickel (12-14%), Carbon (0.04-0.08%), and Manganese (0.5-2.5%), offering outstanding corrosion and oxidation resistance.Their physical properties are a tensile strength of about 80,000 psi, yield strength of 60,000 psi, and elongation of about 30%, which makes them durable and flexible. These electrodes also feature excellent thermal stability, good resistance to creep, and superior impact strength at elevated temperatures, positioning them for operation in high-heat and aggressive environments.

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.
AWS Class E309/309H-16 Electrodes find a broad application base in petrochemical, shipbuilding, power generation, and pressure vessel making industries.These electrodes are ideal for welding those stainless steel pieces that are going to be operating in high temperature conditions, e.g., parts of furnaces, heat exchangers, and boiler tubing. They are also used for overlay welds, cladding, and repairing dissimilar steel structures that require thermal expansion and corrosion protection. They also possess excellent mechanical properties and resist thermal cycling as a result of which they have applications in heavy-duty structural tasks.
AWS Class E309/309H-16 Electrodes are packaged with test certificates that confirm compliance with AWS and industry requirements for excellent performance. The electrodes are offered in various diameters and packaging, such as sealed containers to avoid moisture pickup. Shipment is immediate, customized to suit customer requirements, and made worldwide. The electrodes are packaged securely to preserve product integrity while in transit, presenting a dependable option for industrial welding applications.
