1.1 This specification covers chromium-nickel alloy castings intended for heat-resisting and elevated-temperature corrosion applications, such as structural members, containers, supports, hangers, spacers, and the like, in corrosive environments up to 2000°F [1090°C].

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
