Ti-15V-3Cr-3Sn-3Al
Ti-15V-3Cr-3Sn-3Al is the metastable-beta TIMETAL 15-3 alloy.
Identity / state reference
What distinguishes this material
The source differentiates solution-treated formability from strengths after several ageing cycles.
- Designation in this reference
- Ti-15V-3Cr-3Sn-3Al
- Forms covered by the sources
- Strip
- Sheet
- States to distinguish or confirm
- Solution-treated
- Solution-treated and aged
- Temperature and exposure
- No general service-temperature limit or temperature-independent strength is established by this page. Check the temperature and duration for the specific source table and application.
Property evidence for a stated condition
No condition-specific numerical table is reproduced here
The linked sources establish the identity and the stated product/state scope. Obtain the row for your actual form, section, treatment and test conditions before adopting strength, hardness or a thermal limit.
Resolve these conditions next
- What are the strip gauge, solution-treatment history and exact ageing cycle?
- Obtain the full material certificate, governing specification/edition, product dimensions and test direction before adopting a property value.
For machining, take the exact grade, supplied condition and measured hardness where applicable into the tool maker’s application data. A generic material-family speed is not a substitute for an operation and tool-specific recommendation.
Sources and what they establish
Reviewed 23 October 2026. A source’s publication date and the review date are different. The scope below identifies the fields checked.
TIMET — timetal-15-3-3-3
Producer datasheet for the named alloy; forms, heat treatments, typical/minimum labels and temperatures must be read per table. Legacy publication remains a reference, not a current procurement certificate.
TIMET — timetal-15-3-3-3 ↗Source identity, a named product example and a supplied-batch certificate are different evidence. Cross-standard similarity does not approve substitution.
Corrections from the previous article
- Remove the legacy ASTM Grade 21 similar mapping; the reviewed alloy identity is Ti-15V-3Cr-3Sn-3Al and does not establish that correspondence.
- Replace generic '1000 MPa aged' with the cycle-specific table; do not treat all aged conditions as equivalent.
- Remove the untraceable generic machining recommendation (12 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.
