Request For Our Latest Prices On Duplex Steel Washer S32205 in Mumbai, India!
The Fasteners Mart, based in Mumbai, India, is a prominent manufacturer and exporter of high-quality industrial fasteners and components. Duplex Steel Washers S32205 is one of its high-performance products for application in extreme and corrosive conditions. These washers, usually flat or round, are made of Duplex Stainless Steel UNS S32205, which possesses a dual-phase microstructure of ferrite and austenite. Having outstanding strength and better corrosion resistance, particularly against chlorides and pitting, these washers meet global standards and are used extensively in marine, chemical, and structural applications.
Duplex Steel S32205 Washers consist of around 22% chromium, 5–6% nickel, 3% molybdenum, and balanced levels of nitrogen and manganese. The above composition provides excellent resistance to stress-corrosion cracking, pitting, and crevice corrosion. Mechanically, these washers provide high tensile strength (up to 620 MPa) and yield strength (minimum 450 MPa), along with good elongation and fatigue strength. Physically, Duplex S32205 offers higher hardness and thermal stability and is thus appropriate for high-pressure, high-temperature use in aggressive environments, particularly where other stainless steels would fail.
