Identity / state reference
What distinguishes this material
The reviewed N709 VIM+VAR product is 13-8Mo/XM13; its remelting route is separate from its aging condition.
- Designation in this reference
- 13-8 Mo / UNS S13800
- Forms covered by the sources
- N709 solution-annealed bars, wire and forgings up to the supplier’s 65 mm scope; forging stock has separate scope.
- States to distinguish or confirm
- Solution-annealed delivery; state the subsequent H-condition explicitly.
- Temperature and exposure
- No universal service-temperature limit or room-temperature property set is assigned. Use the cited product document and the purchase certificate.

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 product standard, edition and complete grade are on the material certificate?
- What product form, section size and delivery/heat-treatment condition will be machined?
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.
BÖHLER N709
13-8Mo/XM13, S13800; solution-annealed engineering product and separate forging-stock scope.
BÖHLER N709 ↗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 generic H1000 strength/hardness without the actual section and heat-treatment certificate.
- Withdraw the legacy generic hardness (34–40 HRC (H1000)) and tensile-strength (1,380 MPa (200 ksi)) pair: the old page does not establish a matching product, heat treatment, section and test source.
- Remove the unsupported cutting-speed table and machinability percentage; select tooling only after the actual material condition is known.
