Super Duplex Steel Washers are crafted from alloys that feature a well-balanced austenitic-ferritic microstructure, typically rich in chromium, molybdenum, and nitrogen. This unique composition grants them exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking. On the mechanical side, these washers showcase impressive tensile strength, excellent yield strength, and good toughness, even under high pressure. They also have low thermal expansion and high fatigue resistance, making them ideal for harsh environments that demand durability, reliability, and a long operational lifespan, especially in critical engineering applications around the globe.
Super Duplex Steel Washers find extensive use in industries where high strength and corrosion resistance are crucial. You’ll commonly see them in oil and gas pipelines, offshore platforms, chemical processing equipment, desalination plants, marine structures, and power generation facilities.
