GOST · 3,544 grades # GOST steel grades — 3544 designations — Page 20 Every grade designated under GOST, 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 indicative cross-reference, not an asserted identity — the grades are close, not interchangeable. 11 of 50 rows differ and carry a “This grade’s own name” mark. ##
