BS · 1,547 grades # BS steel grades — 1547 designations — Page 2 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 | |---|---|---|---|---| |
