AISI / SAE · 2,156 grades # AISI / SAE steel grades — 2156 designations — Page 4 Every grade designated under AISI / SAE, 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. 16 of 50 rows differ and carry an “Indicative” mark. ## Also known as 2156 designations |
