Atmospheric corrosion of painted galvanized and 55%Al-Zn steel sheets: results of 12 years of exposure
(Hindawi Publishing Corporation, 2012-01)
Zinc or 55%Al-Zn alloy-coated steel sheets, either bare or covered by different painting systems, have been exposed for 12 years to the action of the urban atmosphere at the CIDEPINT station located in La Plata (34° 50′ ...
Influence of pH on cadmium, copper, and lead removal from wastewater by steel slag
(Desalination Publ, 2016-09)
Steel slag is a byproduct of steel manufacturing which raises an important environmental concern due to the high volume of generation and, specially, its basicity. The aim of this work was to determine its recycling potential ...
Carbon steel passivity examined in alkaline solutions: the effect of chloride and nitrite ions
(Pergamon-Elsevier Science Ltd, 2008-06-09)
The effect of chloride and nitrite ions on the passivity of steel in alkaline solutions was investigated. Four nitrite dosages were tested, resulting in various nitrite/chloride ratios. The behavior of steel was evaluated ...
Influence of Cryogenic Treatments on the Wear Behavior of AISI 420 Martensitic Stainless Steel
(Springer, 2017-11)
The objective of the present work is to characterize the wear behavior of a cryogenically treated low-carbon AISI 420 martensitic stainless steel, by means of ball-on-disk tribological tests. Wear tests were performed under ...
The effect of pre-corrosion and steel microstructure on inhibitor performance in CO2 corrosion
(Pergamon-Elsevier Science Ltd, 2008-09)
The importance of chemical composition and microstructure on CO2 corrosion of carbon and low alloy steels has been widely recognized, still contradictory results can be found in the literature. The aim of this work is to ...
Effect of nickel on the hydrogen stress cracking resistance of ferritic/pearlitic low alloy steels
(NACE International, 2018-07)
Nickel additions to low alloy steels improve mechanical and technological properties. However, Part 2 of ISO Standard 15156 limits the nickel content to a maximum of 1 wt% in oil and gas environments containing H2S because ...
Effect of post-weld heat treatments on SMSS deposit mechanical properties of supermartensitic stainless steel deposit
(Springer, 2017-02)
Supermartensitic stainless steels have good weldability and adequate tensile property, toughness and corrosion resistance. They have been developed as an alternative technology, mainly for oil and gas industries. The final ...
Fracture toughness analysis of a ductile steel by means of 3D surface displacements
(Pergamon-Elsevier Science Ltd, 2013-01)
The standards for characterization of fracture toughness of metals are focused on the calculation of fracture parameters based only on in-plane displacements of the specimen tested. Although fracture is a three-dimensional ...
