Manufacturer or standards-body identification; product values do not apply to every form or condition.
Identity / state reference
What distinguishes this material
Cliffs separates 410 from higher-carbon 420 variants.
- Designation in this reference
- Type 410
- Forms covered by the sources
- Cliffs martensitic sheet/strip coils and cut lengths.
- States to distinguish or confirm
- Annealed supply must be separated from hardened and tempered parts.
- 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.

Cleveland-Cliffs 410 product data
Manufacturer flat-product datasheet; condition and dimensions are product-specific, not all bar, forging or casting supply.
Cleveland-Cliffs 410 product data ↗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
- Replace the single hardened/annealed hardness pair with a specified heat-treatment record; do not treat every 410 product as one hardness.
- Withdraw the legacy generic hardness (155 HB (annealed)) and tensile-strength (480 MPa (70 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.
