MERIH STAINLESS, a reputable manufacturer located in Istanbul, Turkey, specializes in producing top-notch stainless steel welding consumables designed for tough industrial applications. Their AWS Class E309LMo-16 electrodes are specifically crafted for welding stainless steels and for joining dissimilar materials, including stainless and carbon steels. Renowned for their outstanding corrosion resistance and mechanical strength, these electrodes find their place in various industries such as chemical processing, power generation, and marine construction. MERIH STAINLESS is committed to delivering consistent quality and performance, equipping welders with reliable electrodes that ensure smooth arc characteristics, minimal spatter, and easy slag removal for efficient, high-quality welding outcomes.
The AWS Class E309LMo-16 electrode features a composition of about 23–25% Chromium, 12–15% Nickel, and 2–3% Molybdenum, along with a low carbon content (≤0.04%) that boosts corrosion resistance and minimizes carbide precipitation. This unique blend offers exceptional resistance to pitting and crevice corrosion, particularly in environments rich in chlorides. Mechanical properties generally include a tensile strength of ≥550 MPa, yield strength of ≥380 MPa, and elongation of ≥30%. The rutile coating ensures excellent arc stability and a pleasing weld bead appearance, making it suitable for all-position welding and particularly effective for joining dissimilar metals due to its balanced metallurgy and good dilution resistance.
