Overview

ASTM A1007-22: Standard Specification for Carbon Steel Wire for Wire Rope is an internationally recognized standard developed by ASTM International. This specification covers the requirements for uncoated and four classes of round, metallic coated, cold-drawn carbon steel wire used in the manufacture of wire ropes. It establishes a comprehensive framework for the mechanical and chemical properties, dimensional tolerances, coating requirements, and packaging of carbon steel wire for use in wire rope products at five different strength levels.

ASTM A1007-22 is critical to ensuring consistency, safety, and performance in the manufacture and application of wire ropes for construction, industrial, and structural uses. Through standardized testing and clearly defined product requirements, this standard supports manufacturers, purchasers, and end-users in achieving reliable and high-strength wire rope assemblies.

Key Topics

• Wire Types: Specifies both uncoated and metallic coated carbon steel wires available in different strength levels (Levels 1-5).
• Mechanical and Chemical Requirements: Addresses mechanical characteristics such as minimum breaking force, tensile properties, and torsional properties, with chemical composition defined through industry-accepted analyses.
• Coating Classes: Outlines four coating options including drawn-galvanized, final-galvanized, drawn Zn-5Al-MM (zinc-aluminum-mischmetal), and final-coated Zn-5Al-MM, each designed to enhance wire durability and corrosion resistance.
• Dimensional Tolerances: Details strict diameter tolerances and ovality requirements for both uncoated and coated wires, ensuring consistent fit and strength in rope assemblies.
• Testing Procedures: Ensures product quality and reliability through rigorous testing methods, including tensile testing (standard/alternate), torsion testing, and wrap testing as defined by referenced ASTM standards.
• Ordering and Packaging: Describes necessary order information, packaging, and marking in accordance with recognized steel product standards.

Applications

ASTM A1007-22 plays a foundational role in industries where wire rope performance is critical:

• Construction and Structural Engineering: Used for elevator cables, bridge suspension, structural support, and lifting applications where high tensile strength and reliable performance are required.
• Mining and Marine Industries: Ensures safety and durability for hoisting, rigging, towing, and mooring wire ropes in harsh environments.
• Manufacturing: Supports the production of wire rope for cranes, winches, and other machinery requiring precision-engineered steel wire.
• Transportation and Logistics: Applied in cable car systems, aviation controls, and goods handling, where uniform strength and safety are priorities.

The flexible approach to coating and strength classification allows the standard to address varied environmental and mechanical demands, making it highly adaptable across applications.

Related Standards

ASTM A1007-22 references and complements several key standards in the field of steel wire, coatings, and mechanical testing:

• ASTM A90/A90M: Test Method for Weight/Mass of Coating on Iron and Steel Articles
• ASTM A510/A510M: General Requirements for Carbon Steel Wire Rods
• ASTM A700: Guide for Packaging and Marking Steel Products
• ASTM A902 & B899: Terminology for Metallic Coated and Non-Ferrous Metals and Alloys
• ASTM A938: Test Method for Torsion Testing of Wire
• ASTM E8/E8M: Test Methods for Tension Testing of Metallic Materials
• EN 10264-2: European standard for steel wire for wire rope
• ISO 2232: International standard for drawn wire for general-purpose non-alloy steel wire ropes
• API 9A: Specification for wire rope in petroleum applications

These standards collectively facilitate global interoperability, product quality, and safety for carbon steel wire designed for wire rope construction.

3.1 Definitions—For definitions of terms used in this standard, refer to Terminologies B899, A902, and A941.
3.2 Definitions:Definitions of Terms Specific to This Standard:
3.2.1 actual diameter, n—the arithmetic mean of the minimum and maximum diameter measurements in one location on the wire.
3.2.2 breaking forcestrength level (Levels 1,2,3,4 or 5), n—a wire strength based on the minimum load carrying capability of a
designated wire.
3.2.3 drawn-galvanized, drawn-metallic coated, n—a zinc pure zinc, Zn-5Al-MM (Type 5), Type 10, or Type 15 coating that is
applied to the wire prior to the final cold drawing operation by either an electro-deposition or hot-galvanizinghot-dipping process.
3.2.4 drawn-Zn5 Al-MM,final-metallic coated, n—a zinc-aluminum alloy (misch-metal) pure zinc, Zn-5Al-MM (Type 5), Type 10,
or Type 15 coating that is applied to the wire prior to after the final cold drawing operation by a molten coating either an
electro-deposition or hot-dipping process.
3.1.5 final-coated Zn5 Al-MM, n—a zinc-aluminum alloy (misch-metal) coating that is applied to the wire after the final cold
drawing operation by a molten coating process.
3.1.6 final-galvanized, n—a zinc coating that is applied to the wire after the final cold drawing operation by either an
electro-deposition or hot-galvanizing process.
3.2.5 nominal diameter, n—the diameter of the wire expressed in inches (millimetres)(millimeters) and specified by the user to
designate the wire size. It is the basis for the determination of the values of all characteristics of the wire for acceptance purposes.

mm) 1 in. (25.4 mm) of the jaws may be disregarded and a retest performed.
8.1.2 Alternate Testing Method—The tensile test shall be carried out in accordance with Test Methods E8E8/E8M. The loading
rate may be greater than that specified, depending on the number of tests to be carried out for the batch inspection. However, it
shall not exceed the rate corresponding to a 25 % elongation between anchorages in 1 min. The minimum distance between the
clamping jaws of the test machine is 4 in. (100(102 mm). In the event of a dispute, the tensile test shall be carried out strictly in
accordance with Test Methods E8E8/E8M, in particular with regard to the loading rate.
8.1.3 The minimum breaking forcesstrengths are specified in Table 3 of this specification, for uncoated and metallic coated wire
grade Levels 1 through 5. The range in breaking forcestrength for a given grade level is based on the calculated minimum tensile
strength requirement (psi). While no maximum values are shown for breaking force,strength, rope wire is generally produced to
a tensile strength range of 30 000 psi. psi unless an alternative is agreed upon between the purchaser and producer. The resultant
minimum breaking force of either uncoated, drawn-galvanized, and drawn-Zn5 Al-MMstrength of uncoated and drawn-metallic
coated wires of various levels shall meet or exceed the values shown in Table 3. The resultant minimum breaking force for
final-galvanized or final-coated Zn5 Al-MM strength for final-metallic coated wire is obtained by reducing the value stated for its
level in Table 3 for uncoated wire by 10 %. Minimum breaking strength and torsional values for wire diameters not specified within
Table 3 shall be agreed upon between the purchaser and producer.
