(Specification)Standard Specification for Castings, Chromium-Nickel Alloy
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 inch-pound units or SI units are to be regarded separately as standard. Within the test, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
