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): Standard Specification for Castings, Nickel-Aluminum Ordered Alloy defines the requirements for nickel-aluminum ordered alloy castings intended for elevated-temperature and heat-resistant applications. Developed by ASTM International, this standard ensures that the castings are suitable for demanding environments, such as those found in high-temperature industrial furnaces and structural supports where superior heat resistance is crucial. The standard sets out specifications for manufacturing methods, heat treatment, mechanical testing, and chemical composition, supporting quality and consistency across global production.

Key Topics

• Scope of Application: Covers nickel-aluminum ordered alloy castings used in environments up to 2300 °F (1260 °C), including furnace rollers, supports, hangers, and structural members.
• Chemical Composition: Castings must meet strict chemical requirements for elements such as carbon, aluminum, chromium, molybdenum, boron, silicon, iron, and nickel.
• Manufacturing Methods: Allows for various casting methods, such as sand, shell, investment, or centrifugal processes, as agreed upon between purchaser and manufacturer.
• Heat Treatment: Specified by agreement between purchaser and manufacturer when required, to achieve desired material properties.
• Mechanical Properties: Mechanical testing, such as tensile strength, is only mandatory if requested by the purchaser and outlined in the order.
• Testing and Retesting: Tension test samples must represent the full melting practice of the casting. Retesting is permitted if initial results do not meet specific requirements.
• Standard Units: Inch-pound units are standard, with SI units provided for informational reference.

Applications

Nickel-aluminum ordered alloy castings produced according to ASTM A1002-16(2020) are specifically designed for performance in elevated-temperature and high-stress environments. Typical applications include:

• Industrial Furnaces: Furnace rollers, structural supports, hangers, and spacers where exposure to high temperatures is continuous or cyclic.
• Heat-Resistant Structures: Components in containers, supports, and other structural members requiring resistance to thermal stress and oxidation.
• Specialty Components: Utilized in sectors such as chemical processing, power generation, and materials handling where heat resistance and structural integrity are critical.

The specification provides guidance for order placement, including the required alloy grade, need for mechanical or impact tests, and acceptance criteria, ensuring precise communication between manufacturers and purchasers.

Related Standards

For comprehensive quality assurance and consistency, ASTM A1002-16(2020) references and aligns with several other important ASTM standards:

• ASTM A370 - Test Methods and Definitions for Mechanical Testing of Steel Products: Covers procedures for tension and other mechanical testing referenced when mechanical properties are specified in the order.
• ASTM A781/A781M - Specification for Castings, Steel and Alloy, Common Requirements, for General Industrial Use: Outlines the general delivery and supplementary requirements for steel and alloy castings, forming the basis for conformity unless otherwise specified in ASTM A1002.

This standard was developed in accordance with the internationally recognized ISO/IEC guidelines and the World Trade Organization's Technical Barriers to Trade (TBT) principles, facilitating global acceptance and interoperability.
