Duplex 2205 is a two phase ferritic austenitic 22 chromium 3 molybdenum 5 to 6 nickel alloyed stainless steel.
Duplex stainless steel 2205 chemical composition.
The nominal chemical composition of saf 2205 is 22 chromium 5 nickel 3 2 molybdenum and other alloying elements such as nitrogen and manganese.
Stainless steel alloy duplex 2205 uns s32205 duplex 2205 also known as uns s32205 is a nitrogen enhanced stainless steel.
The name 2205 comes from a typical composition of 22 chromium and 5 nickel.
Its high chromium and molybdenum content gives the stainless steel excellent corrosion resistance.
2205 is the most widely used duplex ferritic austenitic stainless steel grade.
Saf 2205 also known as sandvik saf 2205 is a sandvik owned trademark for a 22cr duplex ferritic austenitic stainless steel.
It finds applications due to both excellent corrosion resistance and high strength.
2205 is a duplex stainless steel with a chemical composition of nearly equal proportions of austenite and ferrite.
Due to excellent corrosion resistance and high strength the most widely used duplex stainless steel is 2205.
Other designations for 2205 are given in the table below.
2205 is the most widely used duplex ferritic austenitic stainless steel grade.
This combination allows the alloy to be stronger and tougher than standard austenitic steels.
Users choose duplex 2205 for its excellent corrosion resistance along with its high strength.
The microstructure provides resistance to stress corrosion cracking and ensures high strength.
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.
Combining many of the beneficial properties of both ferritic and austenitic steels 2205 is the most widely used duplex stainless steel grade.
Applications include chemical processing oil and gas exploration marine and other high chloride environments and paper digestors.
Its most important properties are excellent corrosion resistance and high strength.
