Marsh Nickel Alloys, located in Canberra, Australia, is a reputable manufacturer and supplier of top-notch Duplex Steel check valves. Thanks to their state-of-the-art manufacturing facilities and rigorous quality control measures, the company produces check valves that boast outstanding corrosion resistance, strength, and durability. They cater to various industries, including oil and gas, chemical processing, marine, and power generation, offering Duplex Steel check valves that are specifically designed to ensure reliable flow control and prevent backflow, even in the toughest and most corrosive environments.
Duplex Steel check valves are crafted from a unique dual-phase microstructure that combines austenitic and ferritic stainless steel, enriched with high levels of chromium, nickel, molybdenum, and nitrogen. This well-balanced composition grants them exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, Duplex Steel check valves showcase impressive tensile strength, toughness, and fatigue resistance, making them reliable performers under high pressure and temperature conditions.
