BS · 1,547 grades # BS steel grades — 1547 designations — Page 28 Every grade designated under BS, with the material number it maps to, what kind of steel it is, its carbon window and how many other standards carry it. Open a grade for its full composition, properties and its designations in other standards. Every name on this page is an indicative cross-reference, not an asserted identity: the grades are close, not interchangeable. Check the composition before you substitute. ## Also known as 1547 designations | Grade | Material no. | Category | C% by weight | Also in other standards | |---|---|---|---|---| | [LW

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 **Withdrawn** — designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.
