DIN / EN · 4,704 grades # DIN / EN steel grades — 4704 designations — Page 55 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. Every name on this page is recorded in our sources as this standard’s own designation for the grade. ## Also known as 4704 designations | Grade | Material no. | Category | C% by weight | Also in other
