Alloy 2205 duplex stainless steel plate is a 22% Chromium, 3% Molybdenum, 5-6% Nickel nitrogen alloyed duplex stainless steel plate with high general, localized and stress corrosion resistance properties in addition to high strength and excellent impact toughness.
General characteristics of Alloy 2205 Duplex Stainless Steel Alloy 2205 is a duplex stainless steel with a microstructure of austenite plus ferrite. The duplex microstructure, together with the alloy’s chemical composition, result in an excellent combination of strength and corrosion resistance.
Duplex stainless steel. As with all stainless steels, corrosion resistance depends mostly on the composition of the stainless steel. For chloride pitting and crevice corrosion resistance, their chromium, molybdenum and nitrogen content are most important. Chemical tankers are specialized ships carrying liquid cargoes that may be
Stainless Steel Alloy 2205 Alloy 2205 is a ferritic-austenitic stainless steel used in situations that demand good corrosion resistance and strength. Also referred to as Grade 2205 Duplex, Avesta Sheffield 2205, and UNS 31803, some of the more critical design features of Alloy 2205 include:
The carefully controlled chemical composition of the 304 types SS enables The atmospheric corrosion resistance of austenitic stainless steel is unequalled by designed alloys, such as duplex stainless steels, will have to be used where SCC cracking
F51 Duplex Stainless Steel combines improved resistance to stress corrosion cracking, pitting, crevice corrosion and high strength. Due to it's chemical composition F51 duplex stainless steel resists chloride environments and sulphide stress corrosion.
Duplex-grade stainless steel alloys have ferritic/austenitic properties, giving these materials superior strength and excellent resistance to oxidation. While the duplex-grade family includes a wide range of specific formulations, S31803 (2205) and super duplex S32750 (2507) are two of the most common. Chemical Composition Table.
Alloy 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment.
The stainless steel grade can also become embrittled when exposed to temperatures between 300°C and Chemical Composition : The atmospheric corrosion resistance of duplex stainless steels is unequalled by virtually all other uncoated engineering materials. However, SS316 is normally sufficient in areas

Super Duplex Stainless Steel 2507 and Super Duplex Stainless Steel ZERON® 100 are among the most commonly used grades in the family of super duplex stainless steel. Chemical Composition of Duplex Stainless Steel 2507
Duplex stainless steels are stronger and more resistant to corrosion than austenitic and ferritic stainless steels, which makes them useful in storage-tank construction, chemical processing, and containers for transporting chemicals.
Stainless steel is available in many different alloys that incorporate several different elements, but the essential components are iron, carbon and chromium. Low-carbon steel with at least 12-percent chromium forms an even layer of protective oxide on its surface and is, therefore, stainless. In
The 316 family is a group of austenitic stainless steels with superior corrosion from polluted marine environments to areas with sub-zero temperatures. Equipment in the chemical, food, paper, mining, pharmaceutical and petroleum industries often includes 316 Stainless Steel. Nominal Composition in Percent age: Ni 12.00
The microstructure of duplex stainless steel consists resistance, a good weldability and a high strength. The properties of duplex steels depend on their chemical compositions and microstructures. These steels have IMPACT-TOUGHNESS INVESTIGATIONS OF DUPLEX STAINLESS STEELS),
