SAE AMS · 768 grades # SAE AMS steel grades — 768 designations 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?form=bar "bar")[sheet](/materials/ams?form=sheet
