Corrosion Resistant Duplex 2205 Stainless Steel Coil For Biofuels Plants

Hot Rolled Stainless Steel Sheet In Coils 2205 Stainless Steel Coil

2205 Stainless Steel Coil Characteristics:

Alloy 2205 duplex stainless steel coil provides pitting and crevice corrosion resistance superior to 316L or 317L austenitic stainless coils in almost all corrosive media. It also has high corrosion and erosion fatigue properties as well as lower thermal expansion and higher thermal conductivity than austenitic.

2205 Stainless Steel Coil Equivalent Material:

2205 Stainless Steel Coil Corrosion Resistance:

1. General Corrosion:

Because of its high chromium (22%), molybdenum (3%), and nitrogen (0.18%) contents, the corrosion resistance properties of 2205 duplex stainless steel coils are superior to that of 316L or 317L in most environments.

2. Localized Corrosion Resistance:

The chromium, molybdenum, and nitrogen in 2205 duplex stainless steel coil also provide excellent resistance to pitting and crevice corrosion even in very oxidizing and acidic solutions.

3. Stress Corrosion Resistance:

The duplex microstructure is known to improve the stress corrosion cracking resistance of stainless steels.

Chloride stress corrosion cracking of austenitic stainless steels can occur when the necessary conditions of temperature, tensile stress, oxygen, and chlorides are present. Since these conditions are not easily controlled, stress corrosion cracking has often been a barrier to utilizing 304L, 316L, or 317L.

4. Corrosion Fatigue Resistance:

Alloy 2205 duplex stainless steel coil combines high strength and high corrosion resistance to produce high corrosion fatigue strength. Applications in which processing equipment is subject to both an strong corrosive environment and to cycle loading can benefit from the properties of 2205 duplex stainless steel coil.
