AISI / SAE · 2,156 grades # AISI / SAE steel grades — 2156 designations — Page 37 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 indicative cross-reference, not an asserted identity — the grades are close, not interchangeable. 13 of 50 rows differ and carry a “This grade’s own name” mark. ##
