AFNOR · 1,469 grades # AFNOR steel grades — 1469 designations — Page 16 Every grade designated under AFNOR, 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 1469 designations | Grade | Material no. | Category | C% by weight | Also in other standards | |---|---|---|---|---| | [GD
