16Mo3 Flanges are top-notch alloy steel flanges that find their place in pressure vessel and boiler applications, built to handle high temperatures and tough conditions. Crafted from chromium-molybdenum steel, these flanges boast impressive strength, durability, and resistance to both heat and corrosion. Renowned for their stellar performance in high-pressure settings, 16Mo3 Flanges are perfect for welding and forming, making them a go-to choice in power plants, refineries, and the chemical industry. Their sturdy design guarantees reliability, leak-proof connections, and a long lifespan, all while meeting international standards for demanding industrial piping and equipment needs.
These flanges are made up of chromium, molybdenum, and a well-balanced mix of carbon, manganese, silicon, phosphorus, and sulfur. The molybdenum boosts creep resistance and high-temperature strength, while chromium enhances oxidation resistance. With outstanding mechanical properties, including impressive tensile strength, yield strength, and elongation, they can handle high temperatures and pressures without compromising structural integrity. Their toughness and weldability make them versatile for critical operations in industries that require consistent performance and durability under thermal stress.
