Standard Specification for Castings, Chromium-Nickel Alloy
ABSTRACT
This guide covers standard specification for 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. The alloy for the castings shall be made by electric-arc or induction-furnace process. Heat treatment shall be performed wherein the material shall conform to the required chemical composition for carbon, manganese, silicon, sulfur, phosphorus, nitrogen, nitrogen + carbon, iron, titanium, aluminum, columbium, chromium, and nickel. Tensile and Charpy requirements of the alloy used for the casting shall conform to the specified values of tensile strength, yield point, elongation, and unnotched Charpy impact. Mechanical tests like tension test and impact test, if required, shall be made from each melt.
SCOPE
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.
