Mitchell Stainless is a reputable manufacturer and supplier of top-notch stainless steel welding consumables, proudly based in Hamilton, New Zealand. Catering to the fabrication, construction, and heavy engineering sectors across the country, the company has built a solid reputation for its unwavering quality, technical know-how, and reliable supply chain. The AWS Class E309LMo-16 electrodes offered by Mitchell Stainless are specifically crafted for challenging welding tasks that demand exceptional corrosion and crack resistance. These electrodes ensure smooth arc performance and dependable weld integrity, making them perfect for welding dissimilar metals and for use in critical industrial settings.
AWS E309LMo-16 electrodes are made from austenitic stainless steel and are enriched with high levels of chromium and nickel, along with molybdenum to boost corrosion resistance. Their low carbon content minimizes carbide precipitation, which enhances their resistance to intergranular corrosion. In terms of mechanical properties, the weld metal produced offers impressive tensile strength, excellent ductility, and robust impact toughness. The unique coating formulation guarantees stable arc characteristics, efficient slag removal, and a lower chance of hot cracking during the welding process.
