SCC is usually nucleated by some form of localized corrosion in chloride-SCC of stainless steels [68] or aluminum alloys [54], cracks start from areas of pitting, intergranular eorrosion, or crevice eorrosion that create die stress concentration and the acidity required for cracking (Fig. 7). In SCC of C-Mn or low-alloy steels, intergranular corrosion occurs along segregated zones rieh in earbon, nitrogen, or phosphorous and provides a stress concentration (helps to achieve A iscc) [ 7]...

Other methods of metal powder manufacture are also employed for specific metals. Selective corrosion of carbide-rich grain boundaries in stainless steel, a process called intergranular corrosion, also yields a powder. [Pg.182]

Addition of niobium to austenitic stainless steels inhibits intergranular corrosion by forming niobium carbide with the carbon that is present in the steel. Without the niobium addition, chromium precipitates as a chromium carbide film at the grain boundaries and thus depletes the adjacent areas of chromium and reduces the corrosion resistance. An amount of niobium equal to 10 times the carbon content is necessary to prevent precipitation of the chromium carbide. [Pg.26]

Some of the most obvious examples of problems with gas and materials are frequently found in refining or petrochemical applications. One is the presence of hydrogen sulfide. Austenitic stainless steel, normally a premium material, cannot be used if chlorides are present due to intergranular corrosion and subsequent cracking problems. The material choice is influenced by hardness limitations as well as operating stresses that may limit certain perfonnance parameters. [Pg.447]

Intergranular corrosion depends on the length of time the steel is exposed to the sensitizing temperature (500-750°C), even if made from low-carbon or titanium-or niobium-stabilized steel. [Pg.73]

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]
