AISI / SAE · 2,156 grades # AISI / SAE steel grades — 2156 designations — Page 44 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. 3 of 6 rows differ and carry a “This grade’s own name” mark. ## Also known as 2156 designations | Grade | Material no. | Category | C% by weight | Also in other standards | |---|---|---|---|---| | [XM-32](/materials/aisi-sae/xm-32 "XM-32") This grade’s own name | [1.4933](/materials/material-no/1.4933 "1.4933") | Special steels for aviation and aerospace | 0.08–0.13 | 3 | | [XM-32](/materials/aisi-sae/xm-32 "XM-32") This grade’s own name | [1.4939](/materials/material-no/1.4939 "1.4939") | High-temperature steels / aviation variant | 0.08–0.13 | 2 | | [XM-7](/materials/aisi-sae/xm-7 "XM-7") This grade’s own name | [1.4567](/materials/material-no/1.4567 "1.4567") | Stainless steels | ≤ 0.04 | 8 | | [XM8 430 Ti 439](/materials/aisi-sae/xm8-430-ti-439 "XM8 430 Ti 439") | [1.4510](/materials/material-no/1.4510 "1.4510") | Stainless steels | ≤ 0.05 | 14 | | [zależy od producenta](/materials/aisi-sae/zalezy-od-producenta "zależy od producenta") | [1.2703](/materials/material-no/1.2703 "1.2703") | Tool steels for cold work | 0.7–0.78 | 1 | | [М2](/materials/din-en/m-2 "М2") | [1.3343](/materials/material-no/1.3343 "1.3343") | High-speed steels | 0.86–0.94 | 19 | **This grade’s own name** — recorded in our sources as this grade’s own designation under that standard. **Indicative** — taken from a published cross-reference table; a close match, not a guarantee of interchangeability. Verify against the mill certificate before ordering. **Withdrawn** — designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.
