SAE AMS · 768 grades # SAE AMS steel grades — 768 designations — Page 7 Every grade designated under SAE AMS, 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. Every name on this page is an indicative cross-reference, not an asserted identity: the grades are close, not interchangeable. Check the composition before you substitute. ## Also known as 768 designations Product form**All forms**[bar](/materials/ams/page/7?form=bar "bar")[sheet](/materials/ams/page/7?form=sheet
