Stainless steels are high-alloy steels. These steels are available in four groups that include martensitic, austenitic, ferritic and precipitation-hardened steels. These groups are formed based on the crystalline structure of stainless steels.
Stainless steels contain larger amounts of chromium in comparison with other steels and thus have good corrosion resistance. Most of the stainless steels contain about 10% of chromium.
Grade 2205 stainless steel is a duplex stainless steel whose design enables combining improved resistance to pitting, high strength, stress corrosion, crevice corrosion and cracking. Grade 2205 stainless steel resists sulfide stress corrosion and chloride environments.
Products Details
Duplex 2205 is a two-phase, ferritic, austenitic 22% chromium, 3%
molybdenum, 5 to 6% nickel alloyed stainless steel. It is the most
widely used duplex stainless steel grade and is characterized by
high yield strength, double that of the standard austenitic
stainless steel grades. It also demonstrates good fatigue strength,
as well as outstanding resistance to stress corrosion cracking,
crevice, pitting, erosion, and general corrosion in severe
environments.
Chemical Properties
The chemical composition of grade 2205 stainless steel is outlined in the following table.
Element | Content (%) |
---|---|
Iron, Fe | 63.75-71.92 |
Chromium, Cr | 21.0-23.0 |
Nickel, Ni | 4.50-6.50 |
Molybdenum, Mo | 2.50-3.50 |
Manganese, Mn | 2.0 |
Silicon, Si | 1.0 |
Nitrogen, N | 0.080-0.20 |
Carbon, C | 0.030 |
Phosphorous, P | 0.030 |
Sulfur, S | 0.020 |
Properties | Metric | Imperial |
---|---|---|
Tensile strength at break | 621 MPa | 90000 psi |
Yield strength (@strain 0.200 %) | 448 MPa | 65000 psi |
Elongation at break (in 50 mm) | 25.0 % | 25.0 % |
Hardness, Brinell | 293 | 293 |
Hardness, Rockwell c | 31.0 | 31.0 |
Corrosion Resistance
1. Due to its high chromium, molybdenum, and nitrogen content,
Duplex 2205 demonstrates superior corrosion resistant properties to
316 and 316L in most environments
2. Chromium, molybdenum, and nitrogen content also provide high
resistance to pitting and crevice corrosion, even in oxidizing and
acidic solutions
3. Resistant to chloride stress corrosion cracking and temperatures
of up to about 302°F (150°C)
4. The presence of ferrite provides for good performance of Duplex
2205 in caustic environments
Heat Resistance
1. Similar to other duplex stainless steels, Duplex 2205 has good
oxidation resistance at high temperatures
2. Subject to embrittlement when exposed to temperatures above
572°F (300°C) even when exposed for short periods of time; Duplex
2205 is therefore not recommended for use above 572°F (300°C)
