CO2 e concentração de cloreto de 80000ppm, indicando que a resistência ao pite é influenciada por um sinergismo entre a concentração de cloreto e a solução saturada com CO2. This work studies the corrosion resistance of the martensitic stainless steel cast in CO 2-saturated synthetic seawater. A comparison is also made with an aerated solution. The alloy was used in a quenched and tempered condition. The corrosion behavior was evaluated using the cyclic potentiodynamic…

Impedância; Petróleo. abstract The superduplex stainless steels are materials used in severe conditions. The study of the effects of these environments in the material is of great importance, since it prevents subsequent stops for maintenance or exchange of parts due to deterioration by keeping under control the economy of company. This work shows the study of corrosion of the superduplex steel in NaCl 3.5%w, natural sea water, H2SO4 and environment…

increased production resulting from the large bore; however, the tubing must be pulled for service and, being smaller than the pump bore, will cause some fluid acceleration effects. Barrels and fittings are available in a variety of metallurgies. Steel barrels can be furnished in one-piece 36-ft (-m) lengths for all sizes. Onepiece 36-ft brass barrels are available in sizes of 2 /4-in. ID and smaller. Brass barrels 36 ft long with an ID larger than 2-/4 in. are available as an…

CAST AISI 347 STAINLESS STEEL Abstract Nb-stabilized austenitic stainless steels (e. g., AISI 347) can be selected to high temperature services (500oC-800oC), due to the high creep resistance of austenitic structure. Niobium is added to form NbC fine carbides, which has two main functions: prevent intergranular corrosion and increase creep resistance. In the present work it is investigated the importance of the solution and stabilization treatment is as cast structures of AISI 347…

modification of engineering materials. In the case of stainless steels plasma assisted thermochemical treatment, a significant improvement of tribological behavior and corrosion resistance can be achieved, when treatment is performed at low temperatures, below 450 ºC. Among the different plasma-assisted processes, carburizing has shown good results in practical applications, enabling improvements in surface properties of stainless steels by means of carbon diffusion and/or by…
