ASTM A923-Practice A application to identify intermetallic phases in a UNS S32750 superduplex welded joint
(ESCOLA DE MINAS, 2010)
Duplex and superduplex stainless steels present superior mechanical and corrosion properties when compared to usual stainless steels. This superiority is based on chemical composition when in a balanced microstructure ...
Wear and corrosion properties of HVOF coatings from Superduplex alloy modified with addition of boron
(2017-01-15)
Fe-based protective coatings are promising alternatives to replace large or expensive mechanical structures in aggressive environments, such as, in petrochemical industries. In this work, we have evaluated the corrosion ...
Effect of post-weld heat treatment on hardness in superduplex stainless steel astm a890/a890m-grade 6a
(2020-01-01)
Superduplex stainless steel alloy exhibit high mechanical and corrosion resistance, which main industrial application is in the petrochemical industry. The manufacture and maintenance of such equipment usually involve ...
Influence of chloride ion concentration and temperature on the electrochemical properties of passive films formed on a superduplex stainless steel
(ELSEVIER SCIENCE INC, 2010)
Polarization measurements were conducted to monitor the corrosion behavior of superduplex stainless steel ASTM A995M-Gr.SA/EN 10283-Mat#1.4469(GX2CrNiMo26-7-4) when exposed to a) an electrolyte containing 22,700 parts per ...
Characterization of microstructure, chemical composition, corrosion resistance and toughness of a multipass weld joint of superduplex stainless steel UNS S32750
