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,

Magnetostriction of duplex stainless steels

Materials Science and Technology, 1989
AbstractTo identify suitable non-destructive examination techniques, the saturation magnetostriction of a number of ferritic–austenitic (duplex) stainless steel samples from various manufacturers has been measured using a dilatometric technique. The values were found to lie in two distinct ranges, which suggested that two types of material structure ...

Underwater Welding of Duplex Stainless Steel

Solid State Phenomena, 2011
The present work was conducted to assess the weldability of duplex stainless steel at underwater conditions. Interest of underwater welding of this steel grade is connected with necessity of preparing welding repair technologies for subsea pipelines widely used in offshore oil and gas industry.

Sigma-phase in duplex-stainless steels

International Journal of Materials Research, 2004
Abstract The ferritic-austenitic duplex-steels have a very complex precipitation and transformation behaviour, which requires professional treatment. Especially the precipitation of the σ-phase causes considerable changes with regard to the mechanical as well as the corrosive properties, which are to be considered during the treatment of

Magnetic characterisation of duplex stainless steel

Physica B: Condensed Matter, 2006
Heat treatment-induced microstructural processes were studied by different non-destructive magnetic and mechanical material testing methods in the present work. A commercial SAF 2507 type superduplex stainless steel was investigated. This alloy contains about 40% metastable ferrite which can decompose to a sigma phase and secondary austenite due to ...
