NCh · 2 grades

# NCh steel grades — 2 designations

Every grade designated under NCh, with the identifying and comparative data we hold for each. Open a grade for its full composition, properties and its designations in other standards. Every name on this page is recorded in our sources as this standard’s own designation for the grade.

## Also known as

 2 designations

| Grade | Also in other standards |
|---|---|
| [A250ESP](/materials/nch/a250esp "A250ESP") | 1 |
| [A345ESP](/materials/nch/a345esp "A345ESP") | 1 |

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**Withdrawn** — designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.
