Cavitation erosion of duplex and super duplex stainless steels
Scripta Materialia, 1998Owing to their excellent corrosion resistance, stainless steels are widely used both in the marine, urban water, chemical and food industries. In addition to the corrosive environment, high fluid flow speeds are always encountered for components used in these industries.

Failure Cases of Super Duplex Stainless Steel Pump Components
CONFERENCE 2022, 2022Abstract 25 Cr super duplex stainless steel (SDSS) centrifugal pumps have found vast applications in the Oil & Gas industry for produced water injection systems. An important factor in water injection pump material selection is the need to provide adequate corrosion resistance throughout the operating life cycle.

Dissimilar welding of super-duplex and super-austenitic stainless steels
Welding in the World, 2016Dissimilar welding of super-duplex stainless steel 2507 (UNS S32750) to super-austenitic stainless steel 6Mo (UNS S31254) was studied using nickel-alloy filler materials ERNiCrMo-13 and ERNiCrMo-3 as well as super-duplex filler material ER2594 in GTAW. It was shown that mechanical properties of the dissimilar welded joints made with nickel-alloy filler

Materials Science and Technology, 1992
AbstractThis paper presents an overview of duplex stainless steels (DSS) with particular emphasis on super DSS, i.e. steels containing sufficient amounts of chromium, molybdenum, and nitrogen to produce a pitting resistance equivalent greater than 40. Duplex stainless steels have an attractive combination of mechanical and corrosion properties and are ...

Micro Flash Welding of Super Duplex Stainless Steels
Materials Science Forum, 2007Super duplex stainless steels were welded using new flash butt welding technology of temperature controlling system. The super duplex stainless steel (329J4L) and conventional duplex stainless steel (329J3L) were used. The samples were mounted in the dies using a Gleeble thermal simulator and flash but welding was made.

Rolling Texture Formation in Super-Duplex Stainless Steel
Solid State Phenomena, 2010The present research is a part of project which concerns a deformation behavior of duplex type ferritic-austenitic stainless steels. This paper focuses on the examination of ferrite and austenite textures formed upon thermo-mechanical treatment and deformation textures developed during cold-rolling of super-duplex stainless steel sheet.

Technical Challenges in Using Super Duplex Stainless Steel
CORROSION 2006, 2006Abstract Super Duplex Stainless Steel (SDSS) was selected, fabricated and installed for the high pressure, deoxygenated seawater sections of Mars Waterflood Project (MWP). Several factors led to the selection of this material including corrosion resistance in seawater, relatively high strength and the relative uncertainty in the ...

Eddy current techniques for super duplex stainless steel characterization
Journal of Magnetism and Magnetic Materials, 2015Abstract Super duplex stainless steel (SDSS) is a two-phase material where the microstructure consists of grains of ferrite (δ) and austenite (γ). SDSS exhibit an attractive combination of properties, such as: strength, toughness and stress corrosion cracking resistance.
