In practice, three methods are available for preventing sensitisation and intergranular corrosion of austenitic stainless steels ... [Pg.43]

A more detailed treatment of sensitisation of austenitic stainless steels, of intergranular corrosion of austenitic stainless steels without sensitisation, and of sensitisation and intergranular corrosion of ferritic stainless steels and high-nickel alloys, is given by Cowan and Tedmon . [Pg.43]

The risk of intergranular corrosion of austenitic stainless steel can usually be eliminated by ... [Pg.133]

ASTM A-262 [7.21] has standardized five different methods for testing intergranular corrosion of austenitic stainless steels, after Streicher (two), Huey, Warren and Strauss. The Warren test, using exposure to nitric acid-fluoric acid, is particularly suited for molybdenium-alloyed steels. [Pg.134]

In the first mechanism type I), the precipitate is inert or even cathodic with respect to a zone immediately adjacent, which is depleted in elements that promote passivation. The depleted zone being anodic with respect to the rest of the surface it selectively corrodes. Type-I intergranular corrosion is particularly obnoxious under conditions where the zone adjacent to the grain boundary becomes active, while the remainder of the surface remains passive. Intergranular corrosion of austenitic stainless steel due to the precipitation of chromium carbide is the best-known example of type I intergranular corrosion. [Pg.308]

The intergranular corrosion of austenitic stainless steel in molten chlorides can be characterized by electrochemical methods. The results of potentiometry, linear voltammetry and impedance spectroscopy measurements are presented. [Pg.445]

The susceptibihty to intergranular corrosion of austenitic stainless steels after sufficient exposure to temperatures between 427 °C and 871 °C (800 °F and 1600 °F) unless stabilized or low-carbon grades are used. [Pg.388]
