2205 Stainless Sheet

It is has an excellent corrosion resistance including in seawater it is weldable by all standard methods and has a high heat resistance.

2205 stainless sheet. 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. 2205 has been a practical solution to chloride stress corrosion cracking problems experienced with 304 304l or 316 316l 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. This combination allows the alloy to be stronger and tougher than standard austenitic steels.

Alloy 2205 uns s32305 s31803 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. 2205 stainless steel resists cracking even when faced with a combination of tensile stress corrosive chemicals and heat. Also known as duplex stainless steel it has twice the strength of 316 stainless steel. 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 standard of this grade of steel has been refined over the years creating a versatile and strong product. High resistance to stress corrosion cracking scc in chloride bearing environments and environments containing hydrogen sulphide high resistance to general corrosion pitting and crevice corrosion high resistance to erosion corrosion and corrosion fatigue. Duplex 2205 is a two phase ferritic austenitic 22 chromium 3 molybdenum 5 to 6 nickel alloyed stainless steel. 2205 is a duplex stainless steel with a chemical composition of nearly equal proportions of austenite and ferrite.

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. 2205 2205 is a duplex austenitic ferritic stainless steel containing about 40 50 ferrite in the annealed condition. The 2205 grade steel is one of the most widely used ferritic and austenitic duplex stainless steel.
