ASTM B363 is the ASTM International specification covering factory-made seamless and welded unalloyed titanium and titanium alloy butt-welding fittings.
The required titanium grade or alloy, product condition, dimensions and applicable edition should be identified on the purchase order rather than relying on the standard number alone.
What ASTM B363 Covers
- Seamless butt-welding fittings
- Welded butt-welding fittings
- Elbows, tees, reducers, caps and other applicable butt-welding fitting forms
- Grade- or alloy-specific material requirements within the specification.
- Manufacture, dimensions or tolerances, testing, workmanship, certification and marking requirements applicable to the product.
Important Distinction
Avoid restricting B363 to a short historical list of titanium grades. Verify the required grade against the current ASTM edition.

Ordering and Certification
State the complete standard designation and required revision, titanium grade or alloy, product form, dimensions, condition, quantity and any additional testing or certification requirements. The supplied material test report should identify the governing specification and the actual test results applicable to the material.
Standards note: This page is a practical overview and is not a substitute for the official standard. Standards are revised periodically, and requirements can vary by edition, product form and application. Always state the required standard and revision on the purchase order and verify compliance against the applicable specification and material test report (MTR).
