Buyers must specify:

• ASTM designation (B466 or B466M).
• Alloy (UNS number).
• Temper (e.g., annealed, as-drawn).
• Dimensions (OD, wall thickness, length).
• Quantity (total length or number of pieces).
• End finish (e.g., plain, beveled).
• Certification/Test Reports (if required).
• Special Requirements (e.g., hydrostatic testing, non-destructive examination).

Trace elements limited to prevent detrimental effects.

Tensile Strength, Yield Strength, and Elongation requirements vary by temper and alloy.

• Covers OD, wall thickness, and length tolerances.
• Straightness and roundness requirements specified.

• Chemical Analysis: Performed to verify composition (ASTM E478).
• Mechanical Tests: Tensile tests on specimens from finished tubes.
• Hydrostatic Testing: Optional; if required, pressure and duration specified.
• Non-Destructive Testing (NDT): Eddy current or ultrasonic testing upon agreement.
• Visual Inspection: Surface defects must not exceed specified limits.

• Certification: Manufacturer must provide compliance certification (including test results).
• Marking: Each piece must show ASTM standard, alloy, temper, size, and trademark.
