Application Fields Of 2205 Duplex Stainless Steel

Application fields of 2205 duplex stainless steel

Application areas of 2205 duplex stainless steel:

· Pressure vessels, high-pressure storage tanks, high-pressure pipelines, heat exchangers (chemical processing industry).

· Oil and gas pipelines, heat exchanger fittings.
· Sewage treatment system.
· Classifiers, bleaching equipment, storage and handling systems for the pulp and paper industry.
· Rotary shafts, press rollers, blades, impellers, etc. in high-strength and corrosion-resistant environments.
· Ship or truck cargo box
· Food processing equipment

Standard of 2205 duplex stainless steel:
ASTM/ASME..........A240 UNS S32205/S31803
EURONORM............1.4462 X2CrNiMoN 22.5.3
AFNOR............Z3 CrNi 22.05 AZ
DIN........................W. Nr 1.4462

Corrosion resistance of 2205 duplex stainless steel:
uniform corrosion
Due to the chromium content (22%), molybdenum (3%) and nitrogen content (0.18%), the corrosion resistance of 2205 is superior to 316L and 317L in most environments.
Local corrosion resistance
The content of chromium, molybdenum and nitrogen in 2205 duplex stainless steel makes it highly resistant to pitting and crevice corrosion in oxidizing and acidic solutions.
Resistant to stress corrosion
The dual-phase microstructure of stainless steel helps improve the resistance of stainless steel to stress corrosion cracking. Under certain conditions of temperature, stress, oxygen and chloride, austenitic stainless steel will undergo chloride stress corrosion. Since these conditions are not easily controlled, the use of 304L, 316L and 317L is limited in this regard.
Resistant to corrosion fatigue
The high strength and corrosion resistance of 2205 dual-phase steel make it highly resistant to corrosion fatigue. Processing equipment is susceptible to corrosive environments and loading cycles, and the characteristics of 2205 are well suited for such applications.
