2205 Duplex Stainless Steel Tubing/Pipe

1. Uniform corrosion

Due to the chromium content (22%), molybdenum (3%) and nitrogen content (0.18%), the corrosion resistance of 2205 is better than 316L and 317L in most environments.

2. Local anti-corrosion

The content of chromium, molybdenum and nitrogen in the dual phase steel 2205 has strong resistance to the corrosion and corrosion of the surface in the oxidizing and acidic solution.

3. Anti-stress corrosion

The dual phase microstructure of stainless steel helps to improve the corrosion resistance of stainless steel. At a certain temperature, tension, oxygen and chloride in the presence of the case, the austenitic stainless steel will occur chloride stress corrosion. Since these conditions are not easily controlled, the use of 304L, 316L and 317L is limited in this respect.

4. Anti-corrosion fatigue

Dual-phase steel 2205 high strength and corrosion resistance to make it a high anti-corrosion fatigue strength. The processing equipment is susceptible to corrosive environments and the effects of loading cycles, and the 2205 features are well suited for such applications.
