• 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. The main difference between dual certified S32205 and S31830 is the increased corrosion resistance of the S32205 due to the tighter chemistry.

Figure 1. Time—Temperature Precipitation Diagram for 2205 Plate with 0.14 N. precipitate between 800–1500°F (425–815°C), and "885 (425°C) embrittlement" can occur in the temperature range of 650–950°F (340–510°C). If 2205 is held for sufficiently long times in any of these temperature ranges, precipitation reactions will occur.
Scope. 1.1 This specification 2 covers seamless and straight-seam welded ferritic/austenitic steel pipe intended for general corrosive service, with particular emphasis on resistance to stress corrosion cracking. These steels are susceptible to embrittlement if used for prolonged periods at elevated temperatures.
Duplex stainless steels (DSS) are preferred replacement to austenitic stainless steel because of their higher strength leading to economic benefits. However, poor ductility and thermal conductivity along with high toughness make them difficult to machine. In the present investigation, tool wear, cutting force and surface roughness …

Duplex stainless steels are becoming more common. They are being offered by all the major stainless steel mills for a number of reasons: Higher strength leading to weight saving. Greater corrosion resistance particularly to stress corrosion cracking. Better price stability. Lower price. There is a conference on the subject of duplex every 2-3 ...
Duplex 2205 is a nitrogen enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels. "Duplex" describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless. The structure of 2205 duplex ...

Due to excellent corrosion resistance and high strength, the most widely used duplex stainless steel is 2205. The name 2205 comes from a typical composition of 22% Chromium and 5% Nickel. The name 2205 comes from a typical composition of 22% Chromium and 5% Nickel.
1.6 When the SI version of a product specification is required by the purchase order, Specification A788/A788M shall be used in conjunction with Test Methods A1058 instead of Test Methods and Definitions A370. 1.7 The values stated in either SI units or inch-pound units are to be regarded separately as standard.
It can be corrected by complete solution annealing processing. This steel grade works well at temperatures lower than 300oC. The recommended heat processing for Duplex stainless steel 2205 is solution annealing from 1020 to 1100oC then quick quenching. It can be work hardened. It has high strength, fine welding and working properties.

Heat Resistance. The high chromium content of duplex stainless steels that protects against corrosion, causes embrittlement at temperatures over about 300°C. At low temperatures duplex stainless steels have better ductility than the ferritic and martensitic grades. Duplex grades can readily be used down to at least -50°C.

This alloy presents higher mechanical and corrosion resistance properties than standard 22Cr …
Composition. Grade 2205 has a micro structure of roughly equal amounts of ferrite and austenite, hence the 'duplex' description. The duplex structure of 2205 has the following properties: High strength. Lower thermal expansion co-effecient than austenitic steels but greater than carbon steels. High resistance to corrosion, particularly stress ...
