Overview
ASTM B424-22 is the standard specification developed by ASTM International for rolled nickel-iron-chromium-molybdenum-copper alloys plate, sheet, and strip. This standard covers products manufactured from specific alloy grades such as UNS N08642, UNS N06845, UNS N08221, UNS N08825, and UNS N08827. These alloys are known for their excellent resistance to corrosion and high-temperature performance, making them well-suited to demanding industrial applications.
The specification details requirements for chemical composition, mechanical properties, and dimensional tolerances. It is widely referenced for the procurement, fabrication, and certification of nickel alloy materials, ensuring consistency, quality, and reliability in supply chains worldwide.
Key Topics
Chemical Composition
- Product must comply with element ranges for nickel, iron, chromium, molybdenum, copper, and other specified alloying elements.
- Each alloy designation (UNS number) has clearly determined limits for all relevant constituents.
Mechanical Properties
- Minimum mechanical properties such as tensile strength, yield strength, and elongation are specified for each alloy and product form (hot-rolled plate, cold-rolled strip, etc.).
- Mechanical property requirements help ensure material suitability for pressure vessels and other safety-critical applications.
Dimensions and Tolerances
- Prescribed thickness, width, length, squareness, flatness, and edge finish tolerances.
- Products are available as plate, sheet, and strip with defined dimensional ranges.
- Flatness and squareness tolerances help facilitate fabrication, welding, and assembly.
Marking and Documentation
- Every bundle or shipping container is to be marked with the alloy designation, UNS number, specification number, size, and other key contract details.
- Certification requirements and inspection options are clearly outlined to support traceability and quality assurance.
Applications
ASTM B424-22 alloys are utilized across a range of industries where superior corrosion resistance and strength are imperative. Key applications include:
- Chemical Processing
Components exposed to acids, chlorides, and other aggressive chemicals, such as heat exchangers, reactor vessels, and piping, rely on high-performance alloy plates and sheets. - Oil and Gas
Suitable for platforms, piping, and downhole equipment experiencing sour gas, seawater environments, or aggressive chemicals. - Power Generation
Applied in flue gas desulfurization, heat exchangers, and boilers, where alloys must withstand high temperatures, pressures, and corrosive environments. - Pollution Control and Marine Engineering
Used in dampers, scrubbers, seawater desalination equipment, and marine structural components demanding both strength and corrosion resistance.
The plate, sheet, and strip materials specified in ASTM B424-22 are crucial for manufacturing fabricated parts subject to harsh operational conditions, supporting process reliability and safety.
Related Standards
When implementing ASTM B424-22, it is important to consider associated and referenced standards for guidance and compliance, including:
- ASTM B906
General requirements for flat-rolled nickel and nickel alloys plate, sheet, and strip. - ASME SB-424
The ASME Boiler and Pressure Vessel Code equivalent for these alloys, widely required for pressure-containing applications. - UNS Alloy System (ASTM E527, SAE J1086)
Unified Numbering System guidelines for metal and alloy nomenclature.
Related standards help ensure harmonization with industry expectations for quality, performance, and regulatory conformity in nickel-iron-chromium-molybdenum-copper alloy products.

NOTE 1—Permissible variations apply to plates up to 12 ft (3.66 m) in length, or to any 12 ft (3.66 m) of longer plates. If the longer dimension is under
36 in. (914 mm), the permissible variation is not greater than ⁄4 in. (6.4 mm).
NOTE 2—The shorter dimension specified is considered the width, and the permissible variation in flatness across the width does not exceed the tabular
