Titanium
Titanium Grade 2
Commercially pure ASTM Grade 2 is identified with TIMETAL 50A in the producer sheet.
Identity / state reference
What distinguishes this material
The sheet separates a guaranteed minimum yield statement from typical mechanical data; commercially pure does not mean chemically pure.
- Designation in this reference
- ASTM Grade 2 commercially pure titanium
- Forms covered by the sources
- Product form must follow the purchase specification
- States to distinguish or confirm
- Annealed/stress-relieved condition must be confirmed
- 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.

Read the scope above: a source’s related product name is not a blanket interchangeability statement.
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
- Which product standard, condition, thickness and test temperature apply?
- 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-50a
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-50a ↗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
- Do not present 345 MPa as a universal tensile value or 180 HV as all supplied Grade 2 stock.
- Remove the untraceable generic machining recommendation (40 %) and cutting-speed ranges; select machining data by actual material condition, tool and operation.
- The old carbon maximum 0.10% differs from the TIMET 50A sheet 0.08%; replace the unsourced chemistry table with the identified source/specification route.
