Thermodynamics of duplex stainless steels

Materials Science and Technology, 1990
AbstractThe thermodynamic predictions of microstructures in the multicomponent alloys used for duplex stainless steels are discussed in detail in this paper. The production of the duplex ferrite–austenite microstructure by high temperature (1323–1423 K) annealing is considered.

Duplex Stainless Steels for Tanks

CORROSION 2002, 2002
Abstract Due to its poor corrosion resistance, carbon steel is often replaced by stainless steel to build storage tanks for use in water treatment units, food, chemical and para chemical industries. For years, 316L has been widely used. Recently, duplex (austenitic-ferritic) stainless steels have been selected due to improved corrosion ...

Highly alloyed duplex stainless steels

Journal of Materials for Energy Systems, 1985
The corrosion resistance and mechanical properties of thirteen experimental cast duplex stainless steels were evaluated. These 24 pct Cr steels contain 4.5 to 7.5 pct Mo, 7 to 17 pct Ni and 0.2 to 0.4 pct N. The 24Cr- 6Mo- 9.5Ni- 0.25N steel had the best combination of corrosion and mechanical properties.

Friction Welding Duplex Stainless Steel

Offshore Technology Conference, 1988
ABSTRACT Despite the excellent corrosion and high yield strength advantages offered by ferritic-austenitic duplex stainless steel its use for submarine pipelines has been limited because of slow welding procedures and resulting high installation cost.

Super duplex stainless steels

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 ...

Nickel-free duplex stainless steels

Scripta Materialia, 1998
It is well known that nitrogen-alloying in steel produces a variety of exceptional properties such as high strength, high ductility and, eventually, resistance to stress corrosion cracking. High-nitrogen steels (HNS), therefore, have recently been developed to enhance the strength and corrosion resistance of stainless steels.

Welding duplex and super duplex stainless steels

Anti-Corrosion Methods and Materials, 1995
Duplex stainless steels have become important competitors to austenitic stainless steels in many applications and a great deal of attention has focused on the welding aspects. The introduction of modern grades with improved properties and a competitive price level have increased their use in the offshore, petrochemical and shipbuilding industries, for ...

Measuring secondary phases in duplex stainless steels

JOM, 2009
The use of duplex stainless steels is limited by their susceptibility to the formation of dangerous intermetallic phases resulting in detrimental effects on impact toughness and corrosion resistance. This precipitation and the quantitative determinations of the phases have received considerable attention and different precipitation sequences (σ phase ...

Duplex Stainless Steel: Specification Requirements

Offshore Technology Conference, 1993
ABSTRACT The use of duplex stainless steels Offshore has rapidly increased in recent years. At the same time the number of specifications for duplex stainless steel has also rapidly increased. This paper examines the requirements of these specifications, highlights conflicts and questions the need for certain tests.

Corrosion behavior of 2205 duplex stainless steel

American Journal of Orthodontics and Dentofacial Orthopedics, 1997
The corrosion of 2205 duplex stainless steel was compared with that of AISI type 316L stainless steel. The 2205 stainless steel is a potential orthodontic bracket material with low nickel content (4 to 6 wt%), whereas the 316L stainless steel (nickel content: 10 to 14 wt%) is a currently used bracket material.
