Abstract Duplex alloy 2205 is a nitrogen-enhanced, ferritic-austenitic stainless steel. It has high resistance to stress-corrosion cracking (SCC); pitting; crevice and general corrosion. It has roughly twice the yield strength of austenitic stainless grades and it has good weldability. Some uses include heat exchangers, downhole instrument tubing, and applications in desalination plants. All Gibson Tube Duplex 2205 products meet the tighter composition limits of UNS S32205 to enhance corrosion resistance. This datasheet provides information on composition, physical properties, elasticity, tensile properties, and bend strength. It also includes information on corrosion resistance as well as heat treating and machining. Filing Code: SS-813. Producer or source: Gibson Tube.

Abstract AVESTA 2205 is a ferritic-austenitic duplex stainless steel. It resists stress-corrosion cracking very well and has good pitting and general corrosion resistance. Its high strength and stress-corrosion resisting characteristics are a reflection of its duplex microstructure. Its uses include heat exchangers, desalination plants, and pressure vessels that need good resistance to corrosion. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-472.

Selection Of

In earlier works, characterization and stress corrosion cracking of casings of brine recirculation pumps, used in desalination plants, had been investigated. These casings which were manufactured from two types of Ni resist ductile irons have been reported to show different service lives. Material selection of casings is believed to be one of possible factors to extend the service life of these pumps. Two types of stainless steels; UNS S31603 and UNS S32750 have been recommended as substitutes to Ni resist ductile irons. In this work, mechanical, metallurgical, and electrochemical tests have been conducted on as received samples, made of these two types of stainless steels. Results have shown considerable higher yield and tensile strengths and corrosion resistance for the UNS S32750 over the UNS S31603. Results have also shown reproduced pitting behavior illustrated by measured pitting potentials and visual observations for UNS S31603 samples. UNS S32750 samples have shown no signs of pitting.

Abstract. Hot dip galvanizing is being widely used to the numerous constructional steels such as a guard rail of high way, various types of structural steel for manufacturing ship and for some other fields etc.. Recently, the cost of zinc is getting higher and higher, thus, a proper manufacturing process should be developed possibly to reduce the cost of production. In this study, one of hot dip galvanizing process, that is, omission of water washing treatment which is performed after acid cleaning was investigated with some types of flux solution which is added with additives such as acid cleaning solution, NH4OH, Al(OH)3 and H2O2. The decrement of pH by omission of water washing treatment could be recovered to its original value due to neutralization reaction with addition of NH4OH. The flux solution added with both NH4OH and Al(OH)3 exhibited nearly the same color and pH value as those of original flux solution with no added, and the galvanized sample by using this flux solution tended to show a relatively good corrosion resistance compared to other samples treated with different types of flux solution. Furthermore, the flux solution added with NH4OH, Al(OH)3 and H2O2 exhibited a different color as that of original flux solution, and sediments were observed, in addition, its sample exhibited a lower corrosion resistance. Consequently, it is suggested that simplification of process, so-called, omission of water washing treatment may be able to achieve with development of an optimum type of flux solution added with additives.
