Introduction<\/h2>\n\n\n\n

The wrought, corrosion-resistant, nickel-based alloys are vitally important in a number of industries, particularly chemical processing, petrochemical, agrichemical, and pharmaceutical. They exhibit much higher resistance than the stainless steels to many of the key industrial chemicals, and most are inherently resistant to chloride\u2010induced localized attack and stress corrosion cracking. The closely-related, wrought, corrosion-resistant, cobalt-based alloys are used more sparingly, on account of their cost; nevertheless, they provide the added benefit of resistance to certain forms of wear that can be encountered in these same industries.<\/p>\n\n\n\n

The purpose of this manual is to describe the characteristics and attributes of these materials in detail, and, in doing so, pass on much of Haynes International\u2019s practical knowledge in the fields of aqueous corrosion, wear, and metallurgy (of those wrought, nickel and cobalt alloys developed for moderate temperature use).<\/p>\n\n\n\n

For perspective, it should be mentioned that within the realm of nickel and cobalt alloys, these represent just a portion. For example, an equal or greater number of such alloys were developed for, and are used at, high temperatures (>500\u00b0C), notably in flying and land-based gas turbines. Furthermore, numerous wear\u2010resistant cobalt alloys with insufficient ductility for wrought processing are used in the form of castings and weld overlays, in hostile, moderate and high temperature environments.<\/p>\n\n\n\n
