2205 Duplex Stainless Steel Data Sheet

Ugitech s 2205 is a high strength highly corrosion resistant duplex stainless steel with a 22 cr 5 ni and 3 mo compo sition available as uns s31803 or the dual certified uns s31803 s32205.

2205 duplex stainless steel data sheet.

The main difference between dual certified s32205 and s31830 is the increased corrosion resistance of the s32205 due to the tighter chemistry. 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. Grade 2205 is known for offering good localized corrosion resistance to chlorides and saltwater including stress corrosion cracking as well as pitting and crevice corrosion. Duplex stainless steels are neither fully austenitic like 304 stainless nor fully ferritic like 430 stainless.

Saf duplex 2205 stainless steel uns s32205 formerly known as uns s31803 and commonly known as alloy 2205 has a mixed microstructure of austenite and ferrite and is a two phase alloy based on the fe cr ni series.

Alloy 2205 data sheet uns s32205 en 1 4462 uns s 31803 for internal use only. This microstructure ensures that 2205 is much more resistant to stress corrosion cracking than ss 304 or 316l.

Alloy 2205 uns designations s32205 s31803 is a 22 chromium 3 molybdenum 5 6 nickel nitrogen alloyed duplex stainless steel. 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. Ss 2205 is a duplex stainless steel with a microstructure of nearly equal proportions of austenite and ferrite when properly heat treated. 2205is the most widely used duplex ferritic austenitic stainless steel grade.

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. Duplex 2205 is a two phase ferritic austenitic 22 chromium 3 molybdenum 5 to 6 nickel alloyed stainless steel. 2205 has been a practical solution to chloride stress corrosion cracking problems experienced with 304 304l or 316 316l stainless. Duplex steel 2205 fasteners are made from a stainless steel alloy which provides better strength and corrosion resistance than 300 series stainless.
