    Advantage of duplex stainless steel compared with the austenitic stainless steel

       1) In many of the most common medium of 2205 duplex stainless steel corrosion resistance of 316L stainless steel is better than normal, and super duplex stainless steel with high corrosion resistance, in some medium, such as acetic acid, formic acid and so can even replace the high-alloy austenitic stainless steel, corrosion resistant alloys as well.

        2) has a good resistance to localized corrosion, and alloy content of the austenitic phase made of stainless steel compared to the present, it is corrosion resistant to wear and corrosion fatigue performance are superior to austenitic stainless steel.

        3) The coefficient of linear expansion than the austenitic stainless steel is low, and carbon steel close connections for carbon steel and has important engineering significance, such as the production of composite boards or lining and so on.

      4) than the average strength of austenitic stainless steel serving more than twice, and has a plastic molding needs adequate toughness. Use of duplex stainless steel tank or pressure vessel than the common austenitic stainless steel to reduce the thickness of 30-50%, help reduce costs.

        5) has excellent ability of resistance to stress corrosion cracking, especially chloride ions in the environment, even with the lowest amount of duplex stainless steel alloy has a higher resistance than the austenitic stainless steel, the ability of stress corrosion cracking, stress corrosion Common austenitic stainless steel is difficult to solve outstanding problems.
