Standard Specification for Castings, Nickel-Aluminum Ordered Alloy
ABSTRACT
This specification covers nickel-aluminum ordered alloy castings intended for heat-resisting and elevated-temperature applications such as heat-resistant alloy structural members, containers, supports, hangers, spacers, and so forth. The alloy for the castings shall be processed by any method and shall undergo heat treatment. The castings shall conform to the required chemical composition for carbon, sulfur, aluminum, chromium, molybdenum, zirconium, boron, silicon, iron, and nickel. Retests of a duplicate specimen shall be allowed if the elongation of any tension test specimen is less than specific requirement.
SCOPE
1.1 This specification covers nickel-aluminum ordered alloy castings intended for elevated-temperature applications such as heat-resisting alloy furnace rollers, supports, hangers, and so forth, in environments up to 2300 °F (1260 °C).
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.2.1 The SI gage length for tension test specimens is in brackets and is considered standard.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview
ASTM A1002-16(2020) is the international standard specification for castings made from nickel-aluminum ordered alloy. Developed by ASTM International, this standard outlines the requirements for the chemical composition, manufacturing process, and testing of nickel-aluminum alloy castings specifically designed for high-temperature and heat-resistant applications. These castings are frequently used in demanding environments such as furnace rollers, structural supports, containers, spacers, and other components exposed to elevated temperatures up to 2300 °F (1260 °C).
With a focus on ensuring reliability, durability, and performance, ASTM A1002-16(2020) provides essential guidelines for producers, purchasers, and end-users of nickel-aluminum alloy castings.
Key Topics
- Material Scope: Covers nickel-aluminum ordered alloy castings for heat-resisting and high-temperature uses.
- Chemical Composition: Specifies strict chemical requirements including maximum and minimum percentages for key elements like aluminum, chromium, molybdenum, boron, silicon, sulfur, iron, and carbon, with nickel as the balance.
- Manufacturing Methods: Permits flexibility in casting methods - sand, shell, investment, or centrifugal processes - as agreed between manufacturer and purchaser.
- Heat Treatment: Allows for either as-cast or heat-treated delivery, as specified in the purchase agreement.
- Testing and Certification:
- Mechanical testing (e.g., tensile tests) is conducted if specified in the purchase order.
- Test specimens must represent the melt from which the casting is produced.
- Retesting rules ensure that results meet the standard’s requirements.
- International Compliance: Developed in alignment with WTO principles for globally recognized standards.
- Units of Measure: Inch-pound units are standard; SI equivalents are provided for reference.
Applications
Nickel-aluminum ordered alloy castings specified by ASTM A1002-16(2020) are engineered for the following high-temperature and heat-resisting applications:
- Furnace Components: Rollers, hangers, and supports in industrial furnaces that operate up to 2300 °F (1260 °C)
- Heat-Resistant Structures: Structural members and frameworks required to maintain mechanical integrity at elevated temperatures
- Industrial Containers: Containers and spacers exposed to prolonged thermal cycling or corrosive, high-temp environments
- General High-Temperature Equipment: Any application where superior heat resistance, chemical stability, and mechanical strength are required in casting form
These applications are commonly found in sectors such as metal processing, petrochemical industries, power generation, and high-temperature material handling.
