Overview

ASTM B863-23: Standard Specification for Titanium and Titanium Alloy Wire provides the internationally recognized requirements for titanium and titanium alloy wire products. Developed by ASTM International Committee B10 on Reactive and Refractory Metals and Alloys, this specification outlines the necessary chemical, physical, and mechanical properties for a wide range of grades of titanium wire, ensuring consistency, reliability, and safety across various industries.

Titanium and its alloys are prized for their high strength-to-weight ratio, corrosion resistance, and biocompatibility. ASTM B863-23 applies to wire supplied as coils, straight lengths, and welding wire, specifying grades suitable for diverse industrial and commercial applications.

Key Topics

• Scope and Grades
  ASTM B863-23 covers both unalloyed (commercially pure) and alloyed titanium wire, including numerous grades such as:

  • Grade 1 through Grade 39, with both regular and "H" grades (higher minimum ultimate tensile strength), and special alloy compositions featuring aluminum, vanadium, palladium, ruthenium, molybdenum, nickel, and more.
  • Product forms include round, flat, and shaped wire, ranging from 0.005 in. (0.127 mm) up to 0.750 in. (19.05 mm) in thickness or major dimension.

• Chemical Composition
  Detailed chemical requirements are specified for each grade, including maximum levels for elements such as oxygen, iron, carbon, nitrogen, hydrogen, and various alloy additions. This ensures proper performance for mechanical integrity and corrosion resistance.

• Mechanical Properties
  The standard sets out explicit tensile strength, yield strength, and elongation requirements for each grade and product form. For H-grades, higher guaranteed minimum ultimate tensile strength values are mandated, making them suitable for critical applications, such as pressure vessels.

• Physical Properties and Tolerances
  Wire must meet specifications for density, dimensions, and permissible variations in size, as well as requirements for cleanliness, surface finish, and packaging for safe handling and shipping.

• Testing and Certification
  ASTM B863-23 prescribes standard test methods for analyzing chemical composition and mechanical properties, including:

  • Tension testing per ASTM E8/E8M
  • Various chemical and analytical test methods to ensure material conformance
  • Requirements for retesting, reporting, certification, and dispute resolution

Applications

Titanium and titanium alloy wire produced per ASTM B863-23 is used in a wide range of demanding fields for its unique combination of lightness, strength, and corrosion resistance, including:

• Aerospace and Defense: Components, fasteners, and structural applications needing high strength-to-weight ratio and resistance to extreme environments.
• Medical Devices: Surgical implants, dental archwires, and other medical applications, especially with grades that offer excellent biocompatibility.
• Chemical Processing: Wire used in corrosive process environments due to superior resistance to chlorides and other chemicals.
• Marine and Offshore: Fasteners, screens, and components exposed to saltwater and harsh marine conditions.
• Welding and Fabrication: As filler metal or weld wire, conforming to specific restrictions for welding titanium securely and reliably.
• Automotive and Sports Equipment: Lightweight, high-strength components for competitive and recreational use.

Related Standards

Organizations and professionals working with titanium wire should also reference these related standards:

• ASTM E8/E8M: Test Methods for Tension Testing of Metallic Materials
• AWS A5.16/A5.16M: Specification for Titanium and Titanium Alloy Welding Electrodes and Rods
• ASTM E539, E1409, E1447, E1941, E2371, E2994: Test methods for the chemical analysis of titanium and its alloys

ASTM B863-23 promotes uniform quality and interoperability in the supply and application of titanium wire, supporting global engineering, manufacturing, and quality assurance requirements. Proper adherence to this standard helps ensure safety, performance, and compliance across diverse industry sectors.

2.2 AWS Standard:
AWS A5.16 ⁄A5.16M Specification for Titanium and Titanium Alloy Welding Electrodes and Rods
3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 coils, n—wire in coil form with pitch and cast as described by purchaser.
3.1.2 straight lengths, n—wire in straight lengths, generally made by straightening wire from coils by the producer.
3.1.3 weld wire, n—round wire for welding.
3.1.4 wire, n—rounds, flats, or special shapes from 0.005 in. (0.127 mm) to 0.750 in. (19.05 mm) in thickness or major dimension.
4. Product Classification
4.1 Wire—See 3.1.4.
4.2 Coils—Coiled wire may be spooled on spools if required by the user.
4.3 Straight Lengths—After straightening, it may be necessary to perform cleaning or other finishing operations. Straight lengths
are normally 1010 ft to 12 ft long (random). Exact lengths may be specified by the purchaser when necessary.
4.4 Filler Metal or Weld Wire—Wire for welding filler metal application has special requirements for more restrictive chemistry
that allows for oxygen increase inherent in most welding processes used for titanium, and has tighter limits on iron, carbon,
nitrogen, and hydrogen. AWS ER Ti-XX grades are specifically designed for welding the corresponding ASTM XX wrought or
cast material grades. In addition, special requirements for spooling, such as layer winding, cast, and helix, packaging to maintain
cleanliness, and identification are necessary. Use AWS A5.16 ⁄A5.16M for wire for titanium and titanium alloy filler metal.

6. Chemical Composition
6.1 The grades of titanium and titanium alloy metal covered by this specification shall conform to the requirements as to chemical
composition prescribed in Table 1.
6.1.1 The elements listed in Table 1 are intentional alloy additions or elements which are inherent to the manufacture of titanium
sponge, ingot or mill product.
6.1.1.1 Elements other than those listed in Table 1 are deemed to be capable of occurring in the grades listed in Table 1 by and
only by way of unregulated or unanalyzed scrap additions to the ingot melt. Therefore, product analysis for elements not listed in
Table 1 shall not be required unless specified and shall be considered to be in excess of the intent of this specification.
6.1.2 Elements intentionally added to the melt must be identified, analyzed and reported in the chemical analysis.
6.2 When agreed upon by the producer and purchaser and requested by the purchaser in his written purchase order, chemical
analysis shall be completed for specific residual elements not listed in this specification.
6.3 Product Analysis—Product analysis tolerances do not broaden the specified heat analysis requirements, but cover variations
between laboratories in the measurement of chemical content. The manufacturer shall not ship material which is outside the limits
specified in Table 1 for the applicable grade. Product analysis limits shall be as specified in Table 3.
7. Mechanical Requirements
7.1 Annealed material supplied under this specification shall conform to the mechanical property requirements given in Table 2,
as applicable. Material may be ordered in the cold worked condition to higher ultimate tensile strengths and lower elongation levels
as agreed upon between the supplier and the purchaser.
7.2 Tension testing shall be performed in accordance with Test Methods E8E8/E8M. Tensile properties shall be determined using
a strain rate of 0.0030.003 in. ⁄in. ⁄min. to 0.007 in./in./min. (SI equivalent mm/mm/min) through the yield strength, and then the
crosshead speed shall be increased so as to produce fracture in approximately one additional minute.
7.2.1 Wire and shapes with the diameter or smallest dimension between 0.2500.250 in. and 0.125 in. (6.4(6.4 mm to 3.2 mm) shall
have the yield strength determined in accordance with Test Methods E8E8/E8M, and the elongation measured and reported over
4D(4 diameters).
7.2.2 Wire and shapes with the diameter or smallest dimension less than 0.125 in. (3.2 mm) shall have the elongation determined
over 2 in. (50.8 mm) unless defined otherwise by the purchaser. The reported value shall be expressed as a percentage elongation
in 1 in. or 1 in. (25.4 mm) or equivalent.
