What Is 2205 Stainless Steel?
2205 stainless steel is duplex stainless steel – an alloy composed of austenitic and ferritic varieties. The ferritic component makes up approximately 40-50% of the alloy, while the austenitic component makes up the rest. Due to its composition, this alloy has superior mechanical properties compared to traditional 300-series steels made entirely of austenite. This includes greater tensile and yield strength, improved toughness, and more resistance to stress corrosion cracking (SCC).
2205 Stainless Steel Composition
Alloy 2205 stainless steel is a popular material for Inconel sheets due to its superior chemical composition. It contains high levels of chromium and nickel, as well as molybdenum and nitrogen which combine to make it highly corrosion-resistant. It is considered to be duplex stainless steel, meaning it displays characteristics of both the austenitic and ferritic grades of stainless steel, making it harder and stronger than ordinary varieties. As Inconel sheets are often exposed to potentially corrosive substances, it is important that they are made from a solid yet malleable material like 2205 stainless steel. Its multi-faceted alloy offers flexibility in terms of shaping and molding so that it can be used with ease in many different applications.
