Fracture toughness of a welded super duplex stainless steel
Materials Science and Engineering: A, 2014Abstract 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.

National Conference on Challenges in Research & Technology in the Coming Decades (CRT 2013), 2013
The duplex stainless steel (DSS) is a two phase microstructure of about equal proportion of austenite (chromiumnickel) and ferrite (chromium). Austenite is ductile in nature and ferrite is brittle in nature, this combination provides an excellent mechanical properties (hardness, impact toughness etc) and corrosion resistance [1].

Precipitation of secondary phases in super duplex stainless steel ZERON100 isothermally aged
Materials Science and Technology, 2011In 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 ...

Stress corrosion cracking of duplex and super duplex stainless steels in sour environments
Corrosion Science, 1998Abstract 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.

Welding of FERRALIUM alloy SD40 super duplex stainless steel
Anti-Corrosion Methods and Materials, 1996Discusses some aspects of welding of FERRALIUM alloy SD40 and considers differences from the penultimate alloy refinement FERRALIUM alloy 255–3SF. Gives details relating to the metallurgy of FERRALIUM SD 40, noting that it has approximately equal amounts of ferrite and austenite. Reports on methods of achieving the optimum composition after hot working.

Weldability and hydrogen relationships in super duplex stainless steel
1995As 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.
