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.

Duplex Stainless Steels

2008
Abstract This chapter provides information on the structure, design aspects, mechanical properties, forming, machining, and corrosion resistance characteristics of duplex stainless steels. The different types of corrosion covered are general corrosion, pitting corrosion, crevice corrosion, and stress corrosion cracking.

Properties of vacuum sintered duplex stainless steels

Journal of Materials Processing Technology, 2005
This work presents the possibility of obtaining duplex stainless steels through powder metallurgy technology starting from austenitic X2CrNiMo17-12-2, martensitic X6Cr13 powders by controlled addition of alloying elements, such as Cr, Ni, Mo, Cu in the right quantity to obtain the chemical composition of the structure similar to biphasic one.

Pitting Corrosion of Duplex Stainless Steels

Corrosion, 1989
The pitting corrosion of two duplex stainless steels was studied in chloride solutions. Phase compositions were determined by micro-analytical techniques and correlated with pitting behavior. The study showed that the pitting potential and the preferential pitting of the ferrite or austenite phase was dependent upon partitioning of the elements Cr, Mo,
