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**Withdrawn** — designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.
