UNS · 2,038 grades # UNS steel grades — 2038 designations — Page 28 Every grade designated under UNS, 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. 5 of 50 rows differ and carry an “Indicative” mark. ## Also known as 2038 designations |
