SS · 373 grades # SS steel grades — 373 designations — Page 6 Every grade designated under SS, 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 373 designations | Grade | Material no. | Category | C% by weight | Also in other standards | |---|---|---|---|---| |
