GB · 1,318 grades # GB steel grades — 1318 designations — Page 3 Every grade designated under GB, 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. 23 of 50 rows differ and carry an “Indicative” mark. ## Also known as 1318 designations |
