The 2205 grade steel is one of the most widely used ferritic and austenitic duplex stainless steel. The standard of this grade of steel has been refined over the years creating a versatile and strong product. It is has an excellent corrosion resistance (including in seawater), it is weldable by all standard methods, and has a high heat resistance.
Our Duplex 2205 Stainless Steel is a nitrogen-enhanced duplex used in applications requiring high strength and excellent corrosion resistance.It is designed to combine improved resistance to stress corrosion cracking, pitting and crevice corrosion. Duplex 2205 provides nearly double the corrosion resistance typical in other austenitic stainless steels.
Features: 2205 is a duplex stainless steel with nearly equal proportions of austenite and ferrite when properly heat treated.This microstructure makes it much more resistant to stress corrosion cracking than stainless steel 304 and 316L. 2205’s higher chromium, molybdenum and nitrogen contents give it significantly improved pitting and crevice corrosion resistance in the presence of chlorides.
Find the Best of Both Worlds with Duplex 2205 Stainless Steel. Why Duplex Stainless Steel. For jobs that require reliable steel strength and good corrosion resistance, Duplex 2205 Stainless Steel is the key. Because this Duplex stainless steel is both ferritic and austenitic, it combines the top benefits of both alloys.
How to Weld Type 2205 Code Plus Two? Duplex Stainless Steel Outokumpu Stainless Material Description 2205 is a duplex (austenitic-ferritic) stainless steel that combines many of the best properties of austenitic and ferritic stainless steels. High chromium and molybdenum contents provide excellent resistance to pitting and crevice corrosion.

Sandvik SAF 2205, also known as SAF 2205, is Sandvik's trademark for a duplex stainless steel characterized by high resistance to stress corrosion cracking, high resistance to pitting, crevice and general corrosion and very high mechanical strength.
Stainless Steel Duplex Grade 2205 – UNS S32205. A nitrogen, molybdenum enhanced austenitic-ferritic duplex stainless steel with general corrosion resistance similar to 904L; Yield strength nearly double that of austenitic stainless steels. Used in environments where corrosion from chloride stress is an issue
410 Stainless Steel: 2205 is a (two phase) ferritic/austenitic stainless steel with high strength and excellent corrosion resistance, as supplied in the annealed condition with a maximum brinell hardness of 290 (Rc31).
Duplex 2205 stainless steel is characterized by a strong resistance to stress corrosion cracking, crevice, pitting and overall corrosion. In addition, 2205 also has very high mechanical strength. Duplex 2205 us a two phase austenitic, ferritic nickel alloyed stainless steel with a very high yield strength.
Corrosion Resistance of Duplex Stainless Steel Duplex stainless steel exhibit a high level of corrosion resistance in most environments where the standard austenitic grades are used. However, there are some notable exceptions where they are decidedly superior. This results from the alloying that is undertaken. Acids:
This alloy is a lean duplex stainless steel that has a microstructure consisting of austenite and ferrite phases. This duplex microstructure and the chemical composition of 2304 Duplex stainless results in an excellent combination of strength and corrosion resistance. 2304 Duplex stainless possesses good resistance to general corrosion in many acid environments, chloride stress corrosion
1.4462, F55, 2205 duplex stainless steel provides pitting and crevice corrosion resistance superior to 316L or 317L austenitic stainless steels 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.
We compete with the best Bar Suppliers in the world and take pride in maintaining our place among them. Our goal is to supply the highest quality Stainless Steel Bar, Nickel Alloy Bar and Duplex Bar while making it as simple as possible for the customer. Duplex Bar. The real advantage of Duplex Bar is its corrosion resistance.
Ferritic-austenitic stainless steel also referred to as duplex stain - less steels, combine many of the beneficial properties of ferritic and austenitic steels. Due to the high content of chromium and nitrogen, and often also molybdenum, these steels offer good resistance to localised and uniform corrosion. The duplex micro - Steel grades
General corrosion. In most media, Sanmac ? 2205 possesses better resistance to general corrosion than steel of type ASTM 316L and ASTM 317L. Impurities that increase corrosivity are often present in process solutions of acids. If there is a risk of active corrosion, higher-alloyed austenitic stainless steels should be chosen, e.g. Sandvik 2RK65? or Sanicro ? 28.
2205 is a duplex stainless steel that was developed as a cost effective solution to common corrosion problems encountered with 300 series stainless steels. “Duplex” describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like type 430 stainless.
Corrosion Resistance Compared to conventional austenitic stainless steels, like Type 304 and 316, Carpenter 2205 stainless has superior resistance in most oxidizing and reducing acids; superior chloride pitting and crevice corrosion resistance, due to higher chromium, molybdenum and nitrogen content and superior resistance to chloride stress
