ASTM A580/A580M-23

Standard Specification for Stainless Steel Wire

ABSTRACT
This specification covers stainless steel wire, except the free-machining types. It includes round, square, octagon, hexagon, and shape wire in coils only for the more commonly used types of stainless steels for general corrosion resistance and high-temperature service. The steel specimens shall undergo the following conditions: (1) annealed as a final heat treatment; (2) cold worked to higher strength; (3) heat treated to an intermediate temper; or (4) heat treated to a hard temper by austenitizing, quenching, and tempering at a relatively low temperature. The materials shall be cold drawn, annealed, and pickled. The steel wires shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, molybdenum, nitrogen, and other elements such as niobium , vanadium, copper, tantalum, titanium and cobalt. Mechanical test shall be performed wherein in the steel specimens shall conform to the required values of tensile strength, yield strength, and elongation. The martensitic grades shall conform to the required values of hardness after heat treatment.
SCOPE
1.1 This specification covers stainless steel wire, except the free-machining types. It includes round, square, octagon, hexagon, and shape wire in coils only for the more commonly used types of stainless steels for general corrosion resistance and high-temperature service. For bars in straightened and cut lengths, see Specifications A276 or A479/A479M.  
Note 1: For free-machining stainless wire, designed especially for optimum machinability, see Specification A581/A581M.  
1.2 Unless the order specifies the applicable “M” specification designation, the material shall be furnished to the inch-pound units.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.4 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 A580/A580M-23 is the internationally recognized standard specification developed by ASTM International for stainless steel wire, excluding free-machining types. This standard applies to wire produced in coil form with a range of cross-sectional geometries, including round, square, hexagon, octagon, and custom shapes. ASTM A580/A580M-23 specifically addresses stainless steels most commonly used for general corrosion resistance and high-temperature service.

This specification details requirements for the manufacturing, chemical composition, mechanical properties, and heat treatment of stainless steel wire, ensuring consistency and quality across applications in various industries that depend on robust, corrosion-resistant wire products.

Key Topics

• Material Coverage: Stainless steel wire in coils, excluding free-machining types, and available in various shapes for widespread use.
• Specified Grades: Austenitic, ferritic, martensitic, and duplex stainless steel grades recognized for their corrosion resistance and heat tolerance.
• Heat Treatments and Conditions:
  • Annealed (Condition A) for ductility and formability
  • Cold worked (Condition B) for enhanced strength
  • Intermediate temper heat treated (Condition T)
  • Hard temper heat treated (Condition H)
• Required Properties:
  • Chemical composition: Control of elements such as carbon, manganese, chromium, nickel, molybdenum, nitrogen, and others
  • Mechanical properties: Defined minimum requirements for tensile strength, yield strength, and elongation
  • Hardness requirements for martensitic grades post heat treatment
• Manufacturing Requirements: Cold drawn, annealed, and pickled finishes. Specifics about coil diameter, weight, and final finish as per order requirements.
• Measurement Units: Allows for specification and supply in either inch-pound or SI units, but systems must not be mixed in a single order.
• Ordering Information: Purchasers must specify all essential details, such as grade, dimensions, condition, finish, and any special requirements.

Applications

ASTM A580/A580M-23 stainless steel wire is widely used in industries where corrosion resistance, strength, and high performance at elevated temperatures are critical. Principal applications include:

• Automotive Components: Springs, fasteners, wire forms, and exhaust system elements demanding both high strength and resistance to harsh environments.
• Aerospace: Structural wire, control cables, and safety-critical components.
• Industrial Equipment: Basketry, screens, conveyors, and filtration systems operating under corrosive or high-temperature conditions.
• Medical Devices: Surgical instruments, orthodontic wire, and medical appliance components requiring stringent material purity and performance.
• Construction: Wire for reinforcement, architectural features, and structural ties.
• Consumer Products: Kitchenware, hardware, and decorative applications demanding durability and aesthetic appeal.

3.1 It is the responsibility of the purchaser to specify all requirements that are necessary for material ordered under this
specification. Such requirements may include, but are not limited to, the following:
3.1.1 Quantity (weight),
3.1.2 Name of material (stainless steel),
3.1.3 Type or UNS designation (Table 1),
3.1.4 Condition (4.1),
3.1.5 Finish (4.2),
3.1.6 Cross section (round, square, and so forth),
3.1.7 Applicable dimensions including size, thickness, and width,
3.1.8 ASTM designation A580/A580M and date of issue,
3.1.9 Coil diameter (inside or outside diameter, or both) and coil weight, and
3.1.10 Special requirements.
NOTE 2—A typical ordering description is as follows: 5000 lb [2000 kg] Type 304, wire, annealed and cold drawn, ⁄2 in. [13 mm] round, ASTM
Specification A580/A580M dated . End use: machined hydraulic coupling parts.
4. Manufacture
4.1 Condition (Table 2):
4.1.1 Condition A—Annealed as a final heat treatment. Material in Condition A may be given a final cold drawing for size control
or finish, or both, slightly raising tensile strength.
4.1.2 Condition B—Cold worked to higher strength.
4.1.3 Condition T—Heat treated to an intermediate temper generally by austenitizing, quenching, and tempering at a relatively low
temperature.
4.1.4 Condition H—Heat treated to a hard temper generally by austenitizing, quenching, and tempering at a relatively low
temperature.
4.2 Finish:
4.2.1 Cold Drawn—A finish resulting from a final cold drawing pass, generally with cold drawing lubricant left on. Special bright
finishes, lubricant removal, and so forth, for special end uses must be negotiated with the producer.
4.2.2 Annealed and Pickled—A dull matte appearance necessarily associated with the dead-soft condition when no final cold
drawing is permitted.
5. Chemical Composition
5.1 The steel shall conform to the requirements as to chemical composition specified in Table 1.
6. Mechanical Requirements
6.1 The material shall conform to the mechanical test requirements specified in Table 2.
