Weston Stainless, which is headquartered in Midland, UK, is a reliable provider of stainless steel products of the highest quality to various industries including construction, manufacturing, and energy. Among its top-of-the-line welding consumables is the AWS Class E309/309L-16 Electrodes, which is ideal for high-strength and corrosion-resistant applications. The electrodes come in rod form and are made of austenitic stainless steel with low carbon content to prevent carbide precipitation and improve weld integrity. With an AWS Class E309/309L-16 grade, they are perfect for welding dissimilar metals such as stainless steel to carbon steel and where there is a need for high heat and oxidation resistance.
AWS Class E309/309L-16 Electrodes contain a chemical composition of Chromium (23-25%), Nickel (12-14%), Carbon (≤0.03%), and Manganese (0.5-2.5%), which offers better corrosion and oxidation resistance. Their mechanical characteristics have a tensile strength of approximately 80,000 psi, yield strength of 60,000 psi, and elongation of about 30%, providing high ductility and toughness. These electrodes have high thermal stability, good creep resistance, and great impact strength at higher temperatures, making them ideal for challenging welding applications in high-heat applications.
