The microbiologically influenced corrosion (MIC) resistance of a novel Cu-bearing 2205 duplex stainless steel (2205 Cu-DSS) against an aerobic marine Pseudomonas aeruginosa biofilm was investigated. The electrochemical test results showed that Rp increased and icorr decreased sharply after long-term immersion in the inoculation medium, suggesting that 2205 Cu-DSS possessed excellent MIC resista...

steel 2205 is one of the most famous duplex stainless steels. the microstructure of this steel composed of ferrite and austenite in similar amount. therefore, in order to improve mechanical properties through microstructure, thermo mechanical processes such as controlled hot rolling and forging should be applied. it is not possible to employ the usual heat treatment. it shows the importance of ...

In the present review, attempts have been made to analyze the metallurgical, mechanical, and corrosion properties of commercial marine alloy duplex stainless steel AISI 2205 with special reference to its weldability, machinability, and surfacing. In the first part, effects of various fusion and solid-state welding processes on joining DSS 2205 with similar and dissimilar metals are addressed. M...

This paper presents a dislocation-based yield strength model for the nano-indentation size effect. The is based on functional expressions involving densities of statistically stored dislocations and geometrically necessary dislocations. A single-phase austenitic stainless steel (316L) ferrite-austenite dual-phase (2205) are used here as case-study materials to validate proposed model. Experimen...

Service experience from 27 seawater reverse osmosis (SWRO) plants confirms that there is an evident risk of corrosion if wrong steel grade is used for the high pressure piping. Neither 316L nor 317L possesses sufficient corrosion resistance. Not even highly alloyed grades like 2205 and 904L show reliable service performance. However, no corrosion has been reported for 254 SMO, which has been us...

In this research, the effect of shielded metal arc welding (SMAW) process heat input upon microstructure and development heat-affected zone in dissimilar joint API 5L X80/DS5 2205 steels was investigated by recording thermal cycles with thermocouple implantation perpendicular direction weld line. The filler used (electrode) is DSS 2209. base metals their interfaces at different inputs were usin...

An elaborative study was carried out on the growth mechanism and properties of the passive film for a new kind of alloyed corrosion-resistant steel (CR steel). The passive film naturally formed in simulated concrete pore solutions (pH = 13.3). The corrosion resistance was evaluated by various methods including open circuit potential (OCP), linear polarization resistance (LPR) measurements, and ...

Environment safety measurements have resulted in use of peroxide as bleaching chemical in place of chlorine and chlorine dioxide. Concentration and composition of chemicals affects corrosion aspects, the suitability of existing plant metallurgy and materials of construction of bleach plants. Accordingly long term immersion and electrochemical corrosion tests were conducted on stainless steel 30...
