Duplex Stainless Steel Data Sheet

General characteristics ferritic austenitic stainless steel also referred to as duplex stain less steels combine many of the beneficial properties of ferritic and austenitic steels.

Duplex stainless steel data sheet.

The original s31803 composition has over the years been refined by many steel suppliers and the resulting restricted composition range was endorsed as uns s32205 in 1996. Duplex stainless steel plate contains relatively high levels of chromium between 18 and 28 and low to moderate amounts of nickel between 1 5 and 8. 2507 uns s32750 2507 06 2014 2205 code plus two and 254 smo are registered trademarks of outokumpu stainless inc. Ati 2102 uns s82011 alloy is a proprietary lean duplex stainless steel ldss in which the composition is controlled to create a material with the structure and properties of more highly alloyed duplex grades at a lower and more stable cost.

This microstructure ensures that 2205 is much more resistant to stress corrosion cracking than ss 304 or 316l. As a result duplex stainless steels display properties characteristic of both austenitic and ferritic stainless steels. Duplex 2205 data sheet specification the following tables show saf 2205 duplex stainless steel datasheet and specifications such as chemical composition physical properties mechanical properties heat treatment welding etc. 2205is the most widely used duplex ferritic austenitic stainless steel grade.

The alloy has also been applied as a formed and welded sheet product in environments where resistance to general corrosion and chloride stress corrosion cracking is important.

The ati 2205 alloy is the most widely used of the duplex stainless steels and is often used in the form of welded pipe or tubular components. 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. Duplex 2205 is a two phase ferritic austenitic 22 chromium 3 molybdenum 5 to 6 nickel alloyed stainless steel. Their microstructures consist of a mixture of austenite and ferrite phases.
