    Nace Mr0175 Duplex 2205 Pipe ASTM A790 Material High Mechanical Strength


    Production Name : Seamless Duplex Stainless Steel Pipe Standard : ASTM A790 Material : S31803 NACE MR0175



    MATERIAL DESCRIPTION


    Duplex UNS S31803 is the most common duplex grade in the market. It has very good resistance to localized corrosion and stress corrosion cracking in combination with high mechanical strength. It is widely used in oil & gas, hydro power, pressure vessels, pulp & paper, structural components and chemical tankers. The alloy is not intended to be used at temperatures above 300°C due to embrittlement.
