DIN / EN · 4,704 grades # DIN / EN steel grades — 4704 designations — Page 75 Every grade designated under DIN / EN, 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. Unless marked, every name here is an asserted identity — the same grade under this standard’s own designation. 17 of 50 rows differ and carry an “Indicative” mark. ## Also known as 4704 designations |
