# CSA steel grades — 32 designations

Every grade designated under CSA, with the identifying and comparative data we hold for each. Open a grade for its full composition, properties and its designations in other standards. Unless marked, every name here is an asserted identity — the same grade under this standard’s own designation. 8 of 32 rows differ and carry an “Indicative” mark.

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**Withdrawn** — designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.
