MERIH STAINLESS, located in Istanbul, Turkey, stands out as a top manufacturer and supplier of high-quality welding consumables, including the 309LMo MIG and TIG Filler Welding Wire and Rod. Known for their precision engineering and commitment to international standards, MERIH STAINLESS offers products that guarantee reliable, durable, and consistent welds across a variety of industries. With a strong emphasis on innovation, quality control, and customer satisfaction, the company provides solutions tailored for demanding welding applications, supporting projects that require exceptional corrosion resistance and strength. Their 309LMo wires and rods are trusted globally for their performance and reliability in critical welding tasks.
The 309LMo MIG and TIG Filler Welding Wire and Rod are primarily made from austenitic stainless steel, featuring low carbon content and added molybdenum. This unique composition boosts corrosion resistance, especially against pitting and crevice corrosion in environments with chlorides. On the mechanical side, it delivers impressive tensile strength, good ductility, and toughness even at high temperatures. The wire and rod are designed to provide stable arc characteristics, minimal spatter during welding, and strong fusion properties, making them ideal for joining different metals or for overlay applications. They also maintain dimensional stability and resist sensitization, ensuring that weld integrity lasts even in harsh conditions.
