The benefit of a duplex structure is that it combines the favorable qualities of a ferritic alloy (stress corrosion cracking resistance and excessive energy) with these of an austenitic alloy (ease of fabrication and corrosion resistance). The advantage of a duplex is that it blends the fascinating properties of a ferritic alloy with these of an Austin alloy (facility of manufacturing and resistance to corrosion).
Since these conditions usually are not simply managed, stress corrosion cracking has typically been a barrier to utilizing 304L, 316L, or 317L. Although machinable, the excessive strengths of duplex stainless steels makes machining difficult. At low temperatures duplex stainless steels have better ductility than the ferritic and martensitic grades. The duplex microstructure is understood to enhance the stress corrosion cracking resistance of stainless steels.
Continental Steel is a supplier of Duplex 2205 in quite a lot of sizes and shapes together with sheet, coil, plate, plate coil, and extra. All of the Duplex 2205 obtainable through Continental Steel meets industry standards including UNS, ASME, and ASTM. It offers wonderful resistance in marine environments, bleaching, brackish water, closed-loop water systems, and specific food processing purposes. The 2205 high content of molybdenum, chromium, and nitrogen presents superior resistance to corrosion in most circumstances to the standard steels such as 316L and 317L. Usage of 2205 Duplex stainless steel ought to be limited to temperatures under 600° F.
- Duplex 2205 is a two-part, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to six% nickel alloyed chrome steel.
- It is probably the most broadly used duplex stainless-steel grade and is characterised by high yield power, double that of the standard austenitic stainless steel grades.
- Alloy 2205 duplex stainless-steel plate provides pitting and crevice corrosion resistance superior to 316L or 317L austenitic stainless steels in almost all corrosive media.
- It also demonstrates good fatigue power, as well as excellent resistance to emphasize corrosion cracking, crevice, pitting, erosion, and general corrosion in extreme environments.

The chemical evaluation of 2205 duplex chrome steel plate is optimized to acquire a typical 50 a/ 50 g microstructure after resolution annealing therapy at 1900°/1922°F (1040°/1080°C). Chloride stress corrosion cracking of austenitic stainless steels can happen when the required conditions of temperature, tensile stress, oxygen, and chlorides are present.
This allows a designer to avoid wasting weight and makes the alloy more value competitive when in comparison with 316L or 317L. Duplex 2205 Plate are examined to ASTM A923 Method “C” or ASTM G48 Method “A”.
Utilization of chrome steel Duplex 2205 ought to be restricted to below 600 ° F temperature. Unisteel & engineering is a number one producer, exporter & provider of wide range of top of the range Duplex Steel 2205 Sheets, is also known as 2205 steel, and is probably the most extensively used duplex (ferritic/austenitic) stainless-steel grade. The pitting resistance of an austenitic stainless steel could be associated on to alloy composition, the place chromium, molybdenum and nitrogen are a weight %. The Pitting Resistance Equivalent Number (PREN) makes use of the following formula to measure an alloy’s relative pitting resistance – the upper the quantity, the higher the pitting resistance.
