The Super Duplex Steel Washers from Tanvir Nickel Alloys are typically crafted from UNS S32750 or S32760, which feature a unique dual-phase microstructure of austenite and ferrite. The alloy is composed of about 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, giving it remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. These washers boast high tensile strength (up to 800 MPa), excellent fatigue resistance, and solid thermal stability. They come in various types—flat, spring, lock, and custom sizes—to meet specific industrial needs, particularly in applications that demand both mechanical integrity and corrosion resistance under high loads and pressures.
