Stock Size Range and Specifications For Duplex Steel S31803 Sheets & Plates:

S31803 sheet is a type of duplex stainless steel sheet that is designed to provide excellent resistance to corrosion, especially in environments where there is exposure to acids, chloride solutions, and other corrosive substances. UNS S31803 Duplex Stainless Steel Plate is widely used in a variety of applications, ranging from chemical processing equipment, petrochemical plants, to marine and offshore systems.

The S31803 sheet is resistant to various forms of corrosion, including pitting, crevice corrosion, and stress corrosion cracking. ASTM A240 UNS S31803 Duplex Stainless Steel Sheet also offers excellent resistance to high-temperature oxidation and erosion. ASTM A240 UNS S31803 Duplex Stainless Steel Coil is an excellent choice for use in harsh environments where the exposure to corrosive substances is high. The SS UNS S31803 Plate also offers an excellent combination of strength and toughness, making it suitable for use in challenging structural applications that require high strength and corrosion resistance.
