Duplex Stainless Steel 2205 Check Valve

Duplex Stainless Steel 2205 Check Valve Product introduction

　Duplex Stainless Steel 2205 Check Valve Manufacturer, Factory and Supplier In China. Duplex stainless steel 2205 check valve is more and more popular used for high corrosion applications. Duplex stainless steel 2205 check valve has excellent performance of corrosion-resisitant. Also, the duplex stainless steel check valve is particularly resistant to not only chloride stress corrosion but also chloride pitting corrosion. Its PREN value of UNS S31803 is between 38 to 45.

The main application of Duplex stainless steel 2205 check valve includes oil&gas, seawater desalination, shipbuilding, pharmaceutical, petroleum, chemical, and so on.

Duplex stainless steel check valve is also known as 2205, 2507, S31803, S32205, A351 CD3MN, ASTM A182 F51,F53,F55 and 1.4470.

Duplex Stainless Steel 2205 Check Valve feature:

1. Compared with 316L and 317L austenitic stainless steel, duplex stainless steel 2205 alloy has superior performance in pitting corrosion and crevice corrosion. It has high corrosion resistance. Compared with austenite, The coefficient of thermal expansion is lower and the thermal conductivity is higher.

2. Compared with austenitic stainless steel, duplex stainless steel 2205 alloy has twice its compressive strength. Compared with 316L and 317L, the designer can reduce its weight. Alloy 2205 is especially suitable for the temperature range of -50°F to +600°F. Under strict restrictions (especially for welded structures), it can also be used at lower temperatures.

3. Chemical composition: C≤0.030 Mn≤2.00 Si≤1.00 P≤0.030 S≤0.020 Cr 22.0~23.0 Ni 4.5~6.5 Mo3.0~3.5 N0.14~0.20 (austenite-ferrite type).
