Standard Specification for Stainless Steel Needle Tubing
ABSTRACT
The specification covers austenitic, stainless steel, needle tubing in hard-drawn tempers for industrial application. An electric furnace or other similar primary melting process with or without degassing or refining may be used. Needle tubing shall be made by the seamless or welded and drawn process and shall be furnished in the hard-drawn temper condition. Tension tests shall be made to meet the required tensile requirements.
SCOPE
1.1 This specification covers austenitic, stainless steel, needle tubing in hard-drawn tempers for industrial applications.
1.2 In general, needle tubing describes small-diameter tubing with outside diameters (ODs) in the range of 0.008 to 0.203 in. (0.2 to 5.2 mm) with nominal wall thicknesses in the range of 0.002 to 0.015 in. (0.05 to 0.4 mm). Needle tubing gages are normally 6 through 33.
1.3 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.
1.4 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 A908-03(2019): Standard Specification for Stainless Steel Needle Tubing defines requirements for austenitic stainless steel needle tubing in hard-drawn tempers, primarily used in industrial applications. This specification covers tubing manufactured by seamless or welded and drawn processes, supplied in a hard-drawn condition, and subject to strict mechanical and dimensional requirements. The standard supports international trade by adhering to WTO Technical Barriers to Trade (TBT) Committee principles.
Key Topics
Material Scope:
- Austenitic stainless steel, typically Type 304 (UNS S30400), is used.
- Tubing is produced via seamless or welded and drawn methods for enhanced performance.
- Tubing is furnished in the hard-drawn temper condition, ensuring high strength and consistent properties.
Dimensional Requirements:
- Outside diameters (ODs) range from 0.008 to 0.203 in. (0.2 to 5.2 mm).
- Wall thicknesses range from 0.002 to 0.015 in. (0.05 to 0.4 mm).
- Tubing gauges are generally 6 through 33, with tight tolerances for both OD and wall thickness as specified in Table 3 of the standard.
Mechanical Properties:
- Tensile strength requirements: 150–200 ksi (1030–1370 MPa).
- Two tension tests required for every 5000 feet of product per heat.
Chemical Composition:
- Strict limits on elements such as carbon (max 0.08%), manganese (max 2.00%), phosphorus (max 0.040%), sulfur (max 0.030%), and silicon (max 0.75%).
- Chromium and nickel content ranges, ensuring corrosion resistance.
Testing and Certification:
- Order details must specify quantity, gauge or size (OD and wall), length, and whether test reports are required.
- Chemical and product analysis ensure composition consistency.
- Documentation and certification as per ASTM A1016/A1016M requirements.
Applications
ASTM A908-03(2019) stainless steel needle tubing is widely used for:
Industrial Instrumentation:
Precise fluid transfer and sampling lines due to small diameter and high strength.Medical and Laboratory Devices:
Components in hypodermic needles, catheters, and sampling equipment, benefiting from cleanliness and corrosion resistance.Chemical Processing:
Small-diameter lines for chemical injection and control in corrosive environments.Aerospace and Electronics:
Intricate tubing assemblies where precise dimensions and mechanical strength are critical.
Using ASTM-compliant stainless steel needle tubing helps manufacturers meet global quality, safety, and performance benchmarks.
Related Standards
For quality assurance and compatibility, the following standards are commonly referenced with ASTM A908:
- ASTM A1016/A1016M: General requirements for ferritic and austenitic alloy steel and stainless steel tubes.
- ASTM A213/A213M: Seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes.
- ASTM A269: Welded and seamless austenitic stainless steel tubing for general service.
- ISO and EN standards may also align with ASTM A908 for international acceptance.
Practical Value
Adhering to ASTM A908-03(2019) ensures stainless steel needle tubing has:
- Consistent dimensions and tolerances for reliable assembly.
- High mechanical strength suitable for demanding environments.
- Detailed chemical composition for corrosion resistance and performance.
- Traceability and documentation that streamline procurement, compliance, and project quality control.
Selecting ASTM A908 needle tubing promotes operational efficiency, safety, and regulatory compliance across global supply chains.
