MERIH STAINLESS, located in Istanbul, Turkey, stands out as a top manufacturer of stainless steel welding consumables, including the AWS Class E309/309L-16 electrodes. These electrodes are specifically designed for welding austenitic stainless steels to carbon steels, making them perfect for joining different types of metals. With a commitment to high-quality standards, MERIH STAINLESS guarantees that these electrodes deliver reliable arc stability, minimal spatter, and easy slag removal. Their products cater to a variety of industries, such as chemical processing, power generation, and shipbuilding, ensuring strong and durable welds even in tough environmental and thermal conditions.
The AWS Class E309/309L-16 electrodes boast a composition of about 23–25% Chromium, 12–14% Nickel, and a low carbon content (≤0.04% for 309L), which provides outstanding resistance to oxidation and corrosion, particularly in high-temperature settings. These electrodes typically achieve a tensile strength of ≥520 MPa, yield strength of ≥240 MPa, and elongation of ≥30%. Their rutile coating ensures smooth arc performance and a pleasing weld bead appearance, along with excellent slag detachability. The low carbon 309L variant helps minimize carbide precipitation, which prevents intergranular corrosion in the welded areas, ensuring top-notch weld quality.
