The tubes are made from the following nickel alloys: aluminum, boron, carbon, chromium, cobalt, columbium, copper, iron, manganese, molybdenum, nickel, phosphorous, silicon, sulphur, titanium, tungsten, and vanadium. Anticipated uses cover applications where strength and strength at elevated temperatures are desired attributes. Some examples are hydraulic control lines, boilers, heat exchangers, and solar absorbers. The tubes shall be supplied in one of the following conditions: cold worked, cold worked and precipitation hardened, solution annealed plus precipitation hardened, or solution annealed and descaled conditions. When atmosphere control is used, descaling is not necessary.
This specification also covers ordering information, chemical and mechanical requirements, heat treatments, conditions representing different levels of mechanical properties, hydrostatic or nondestructive electric test, surface condition, weight, and workmanship, finish, and appearance.

Overview
ASTM B1007-21: Standard Specification for Welded Precipitation Hardenable or Cold Worked, Nickel Alloy Tube is an internationally recognized standard developed by ASTM International. This specification establishes requirements for the manufacture, chemical and mechanical properties, heat treatments, and testing of welded nickel alloy tubes. Covered products include both nominal and minimum wall-thickness tubes, intended for high-strength and high-temperature applications such as hydraulic control lines, boilers, heat exchangers, and solar absorbers. The standard supports engineering and procurement professionals by promoting consistent product quality in demanding environments.
Key Topics
- Scope and Materials: Applicable to welded tubes ranging from 1/8 to 6 inches (3.2 to 152.4 mm) in outside diameter and 0.015 to 0.148 inches (0.41 to 3.7 mm) in wall thickness, using various nickel alloys (e.g., UNS N07725, N07740, N09945, N09946, N09925, N07718, N10276, N06985).
- Product Conditions: Tubes may be provided as cold worked, cold worked and precipitation hardened, solution annealed plus precipitation hardened, or solution annealed and descaled. Bright annealing may eliminate the need for descaling.
- Mechanical and Chemical Requirements: Includes limits for tensile strength, yield strength, elongation, and chemical composition per Table 1 of the standard. Testing is required on a lot basis to ensure compliance.
- Manufacturing Processes: Specifies fusion welding with inert gas shielding and no filler metal, as well as subsequent bead working and solution annealing. Additional mechanical manipulation tests and hardness testing are required for quality control.
- Testing and Inspection: Each tube must undergo either hydrostatic or nondestructive electric testing (e.g., eddy current, ultrasonic) as defined in referenced ASTM standards. Tubes must also meet criteria for workmanship, finish, straightness, and surface quality.
- Ordering Information: Purchasers are responsible for specifying alloy, tube dimensions, end requirements, certification needs, and inspection preferences to ensure delivered products meet intended application needs.
Applications
The welded precipitation hardenable and cold worked nickel alloy tubes covered by ASTM B1007-21 provide exceptional mechanical strength and resistance to high temperatures, making them ideal for:
- Hydraulic Control Lines: Where reliability and leak resistance are critical under high pressure and temperature.
- Boilers: For enduring cyclic loading and thermal stresses in power generation and industrial heating systems.
- Heat Exchangers: Providing corrosion resistance and high durability in aggressive environments, including chemical processing and energy sectors.
- Solar Absorbers: Utilizing precise tolerances and elevated temperature strength for efficient thermal transfer.
- General High-Performance Tubing: In locations requiring trusted resistance to mechanical stress and corrosion, especially in chemical, petrochemical, and marine industries.
Related Standards
ASTM B1007-21 integrates and references several key standards to ensure robust and harmonized product requirements:
- ASTM B751/B751M: General requirements for nickel and nickel alloy welded tubes.
- ASTM B880: Specifications for chemical check analysis limits for nickel, nickel alloys, and cobalt alloys.
- ASTM B899: Terminology relating to non-ferrous metals and alloys.
- ASTM E8/E8M: Test methods for tension testing of metallic materials.
- ASTM E527: Practice for numbering metals and alloys in the Unified Numbering System (UNS).
Practical Value
ASTM B1007-21 supports manufacturers, engineers, and procurement specialists seeking reliable, high-strength welded nickel alloy tubes for industrial and commercial projects. Adhering to this specification ensures consistency, safety, and performance in critical applications exposed to demanding operational conditions.

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.
Designation: B1007 − 17 B1007 − 21
Standard Specification for
Welded Precipitation Hardenable or Cold Worked, Nickel
Alloy Tube
This standard is issued under the fixed designation B1007; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope Scope*
1.1 This specification covers nominal and minimum wall-thickness welded tubes and welded and cold worked tubes made from
the nickel alloys listed in Table 1. Anticipated uses cover applications where strength and strength at elevated temperatures are
desired attributes. Some examples are hydraulic control lines, boilers, heat exchangers, and solar absorbers.
1.2 Tube shall be supplied in one of the following conditions; cold worked, cold worked and precipitation hardened, solution
annealed plus precipitation hardened, or solution annealed and descaled conditions. When atmosphere control is used, descaling
is not necessary.
1.3 This specification covers tube ⁄8 to 6 in. (3.2 to 152.4 mm) in outside diameter and 0.015 to 0.148 in. (0.41 to 3.7 mm)
inclusive in wall thickness.
1.4 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.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility
of the user of this standard to become familiar with all hazards including those identified in the appropriate Safety Data Sheet
(SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental
practices and determine the applicability of regulatory limitations prior to use.
1.6 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.
