Manufacturer or standards-body identification; product values do not apply to every form or condition.
Identity / state reference
What distinguishes this material
The supplier separates annealed strip from tempered strip in its 1070/1074/1075 range; the suffix/temper is essential to a useful 1075 page.
- Designation in this reference
- SAE 1075
- Forms covered by the sources
- Gibbs strip product range.
- States to distinguish or confirm
- Annealed strip and tempered strip are separate purchase conditions.
- 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.

Gibbs Interwire strip catalogue
Separately catalogued 1070/1074/1075 annealed and tempered strip; grouped commercial listing is not proof that grades are interchangeable.
Gibbs Interwire strip catalogue ↗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 turn the supplier grouped 1070/1074/1075 listing into exact grade equivalence or assume every 1075 part is annealed.
- Withdraw the legacy generic hardness (217 HB) and tensile-strength (740 MPa (107 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.
