They are characterised by high hardness, wear resistance and the ability to retain a sharp or precise working edge, making them suitable for dies, punches, cutting tools and other tooling exposed to repeated mechanical contact. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 31 designations · 17 standards · nothing hidden This grade’s own name recorded in our sources as this grade’s own designation under that standard. Indicative taken from a published cross-reference table; a close match, not a guarantee of interchangeability. Verify against the mill certificate before ordering. Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Elements not listed have no value on file — they are omitted, never inferred. ## Predicted transformation temperatures Not enough recorded composition to predict a transformation temperature for this grade — missing: Ni, Mo. ## Physical & mechanical properties Density 7,6 g/cm³ Exact An absent property means we hold no value for it — it is left out rather than estimated, interpolated from a neighbouring grade, or filled from a handbook. It does not mean the property is undefined for the material. ## Properties by condition 4 conditions · 7 values By delivery state**no delivery state stated** source `steeljis` | Delivery state | HB | HRC | |---|---|---| | Annealed | 255 | — | | Quenched and tempered | — | 62 | By delivery state**Soft annealed** source `steelnumber` | Delivery state | HB | |---|---| | Soft annealed | 255 | By delivery state**no delivery state stated** source `splav` | Delivery state | Rm N/mm² | A5% | |---|---|---| | Sheet cold-rolled, GOST 21427.2-83 | 330 – 470 | 20 – 35 | At temperature**no delivery state stated** source `splav` | Temperature °C | Density g/cm³ | Electrical resistivity nΩ·m | |---|---|---| | 20 | 7.75 | 400 | Every figure holds only for the condition on its own row.

These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
