Duplex Stainless Steel Instrumentation Valves are crafted from a balanced blend of austenitic and ferritic stainless steels, which gives them exceptional strength and resistance to corrosion. Typically, these valves contain about 22–25% chromium, 5–6% nickel, 3–5% molybdenum, and trace amounts of nitrogen to boost their mechanical properties. They showcase high tensile strength, impressive toughness, and resistance to stress corrosion cracking, especially in chloride-rich environments. The unique duplex microstructure combines the best features of both steel types, resulting in improved fatigue resistance, enhanced durability under high-pressure conditions, and long-lasting reliability in aggressive chemical and marine applications.
