Fracture toughness of a welded super duplex stainless steel

Materials Science and Engineering: A, 2014
Abstract Fracture toughness testing was conducted on standard single-edge notched bend bar specimens of base and weld metal. The material was the SAF 2906 super duplex stainless steel. The aim was to evaluate the susceptibility for brittle failure at sub-zero temperatures for the base and weld metal.

Rolling Texture Formation in Super-Duplex Stainless Steel

Solid State Phenomena, 2010
The 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.

Weldability and hydrogen relationships in super duplex stainless steel

1995
As the microstructure of commercial duplex stainless steels consists of approximately 50% austenite and 50% ferrite, the response of these two phases to hydrogen is of interest to the users of these materials. A study has been made of the hydrogen cracking behaviour in welded super duplex stainless steel using the GTA welding process.

A New Method of Material Categorisation for Super-Duplex Stainless Steel Tubulars

Proceedings of SPE High Pressure/High Temperature Sour Well Design Applied Technology Workshop, 2005
Summary Following the failure of a super-duplex stainless steel (SDSS) production tubular in an HT-HP well in the Shearwater field, Shell Exploration & Production in Europe have developed a new method of categorizing SDSS material using an eddy current inspection technique.

Influence of Annealing on Structure and Corrosion Resistance of Duplex and Super Duplex Stainless Steel

2020
One of the basic criteria determining the suitability as a structural material is its corrosion resistance. In addition, abrasion resistance, heat resistance, mechanical strength are also important. The properties of austenitic-ferritic two-phase Duplex steels resulted in its various applications, among others, in radiators, dryers, structures working ...

Stress corrosion cracking of duplex and super duplex stainless steels in sour environments

Corrosion Science, 1998
Abstract The resistance of two commercial duplex stainless steels to sulphide stress corrosion cracking in sour environments has been assessed by means of slow straining in a variety of solutions saturated with hydrogen sulphide over the temperature range from 2 to 95°C.

Precipitation of secondary phases in super duplex stainless steel ZERON100 isothermally aged

Materials Science and Technology, 2011
In the present paper the results of secondary phases determination and quantification in ZERON100 duplex steel, heat treated at 850–1000°C for 180–2400 s, are presented. During the isothermal heat treatments, at 850°C, the χ phase is the only phase to precipitate at α/ γ boundaries and triple points, while at 900 and 950°C, χ phase is the first phase ...

The Performance of a Super-Duplex Stainless Steel in Chloride Environments

CORROSION 1990, 1990
Abstract UNS S32750, a so called super-duplex stainless steel, has been investigated using many test techniques in various aqueous chloride environments. The results show that the UNS S32750 alloy has superior resistance to localized attack as compared to most other stainless steels.

On the Role of HISC on Super and Hyper Duplex Stainless Steel Tubes

OTC Brasil, 2013
Abstract The Super duplex stainless steels (SDSS) are characterized by a remarkable combination of corrosion resistance and mechanical strength, mainly in chloride containing environments. Because of this, its demand is growing every year in offshore applications, becoming an alternative to the ferritic and ...

Precipitation of Chromium Nitrides in the Super Duplex Stainless Steel 2507

Metallurgical and Materials Transactions A, 2015
Precipitation of chromium nitrides during cooling from temperatures in the range 1373 K to 1523 K (1100 °C to 1250 °C) has been studied for the super duplex stainless steel 2507 (UNS S32750). Characterization with optical, scanning and transmission electron microscopy was combined to quantify the precipitation process.
