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 42 designations · 21 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Flake sensitivity not susceptible As published: not predisposed Temper brittleness not susceptible As published: not predisposed 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 · 5 values By delivery state**no delivery state stated** source `steeljis` | Delivery state | HB | HRC | |---|---|---| | Annealed | 255 | — | | Quenched and tempered | — | 58 | By delivery state**Soft annealed** source `steelnumber` | Delivery state | HB | |---|---| | Soft annealed | 255 | By delivery state**no delivery state stated** source `splav` | Delivery state | HB | |---|---| | (annealing) , GOST 5950-2000 | 255 | At temperature**no delivery state stated** source `splav` | Temperature °C | Electrical resistivity nΩ·m | |---|---| | 20 | 640 | Every figure holds only for the condition on its own row. Values are never merged across conditions or across sources, never averaged, and never interpolated between two rows. An em dash means no value on file — never zero. Figures are converted to the unit in the column header; the source’s own wording is kept and shown where the two differ. ## Similar grades — and why Selection rule, stated so you can disagree with it: same number class 1.2, a shared category, and a published range for Cr / V that overlaps this grade’s. These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
