UNE · 760 grades # UNE steel grades — 760 designations — Page 12 Every grade designated under UNE, 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 760 designations | Grade | Material no. | Category | C% by weight | Also in other standards | |---|---|---|---|---| | [F.5233](/materials/une/f-5233 "F.5233") | [1.2419](/materials/material-no/1.2419 "1.2419") | Tool steels for cold work | 1–1.1 | 16 | | [F.5241](/materials/une/f-5241 "F.5241") | [1.2542](/materials/material-no/1.2542 "1.2542") | Tool steels for cold work | 0.4–0.5 | 12 | | [F.5241 45 WCrSi 8](/materials/une/f-5241-45-wcrsi-8 "F.5241 45 WCrSi 8") | [1.2542](/materials/material-no/1.2542 "1.2542") | Tool steels for cold work | 0.4–0.5 | 12 | | [F.528](/materials/une/f-528 "F.528") | [1.2713](/materials/material-no/1.2713 "1.2713") | Tool steels for cold work | 0.5–0.6 | 12 | | [F.5313CrMoV12](/materials/une/f-5313crmov12 "F.5313CrMoV12") | [1.2365](/materials/material-no/1.2365 "1.2365") | Tool steels for hot work | 0.28–0.35 | 18 | | [F.5317X37CrMoV5](/materials/une/f-5317x37crmov5 "F.5317X37CrMoV5") | [1.2343](/materials/material-no/1.2343 "1.2343") | Tool steels for hot work | 0.33–0.41 | 20 | | [F.5318](/materials/une/f-5318 "F.5318") | [1.2344](/materials/material-no/1.2344 "1.2344") | Tool steels for hot work | 0.35–0.42 | 20 | | [F.5318](/materials/une/f-5318 "F.5318") | [1.2343](/materials/material-no/1.2343 "1.2343") | Tool steels for hot work | 0.33–0.41 | 20 | | [F.5318](/materials/une/f-5318 "F.5318") | [1.2311](/materials/material-no/1.2311 "1.2311") | Tool steels for cold work | 0.35–0.45 | 12 | | [F.5318X40CrMoV5](/materials/une/f-5318x40crmov5 "F.5318X40CrMoV5") | [1.2344](/materials/material-no/1.2344 "1.2344") | Tool steels for hot work | 0.35–0.42 | 20 | | [F.5320](/materials/une/f-5320 "F.5320") | [1.2581](/materials/material-no/1.2581 "1.2581") | Tool steels for hot work | 0.25–0.35 | 18 | | [F.5323](/materials/une/f-5323 "F.5323") | [1.2581](/materials/material-no/1.2581 "1.2581") | Tool steels for hot work | 0.25–0.35 | 18 | | [F.5520](/materials/une/f-5520 "F.5520") | [1.3355](/materials/material-no/1.3355 "1.3355") | High-speed steels | 0.73–0.83 | 22 | | [F.5530](/materials/une/f-5530 "F.5530") | [1.3255](/materials/material-no/1.3255 "1.3255") | High-speed steels | 0.75–0.83 | 14 | | [F.5540](/materials/une/f-5540 "F.5540") | [1.3265](/materials/material-no/1.3265 "1.3265") | High-speed steels | 0.72–0.8 | 6 | | [F.5563](/materials/une/f-5563 "F.5563") | [1.3202](/materials/material-no/1.3202 "1.3202") | High-speed steels | 1.3–1.45 | 12 | | [F.5601](/materials/une/f-5601 "F.5601") | [1.3355](/materials/material-no/1.3355 "1.3355") | High-speed steels | 0.73–0.83 | 22 | | [F.5603](/materials/une/f-5603 "F.5603") | [1.3343](/materials/material-no/1.3343 "1.3343") | High-speed steels | 0.86–0.94 | 19 | | [F.5605](/materials/une/f-5605 "F.5605") | [1.3344](/materials/material-no/1.3344 "1.3344") | High-speed steels | 1.15–1.25 | 8 | | [F.5607](/materials/une/f-5607 "F.5607") | [1.3348](/materials/material-no/1.3348 "1.3348") | High-speed steels | 0.95–1.05 | 8 | | [F.5607](/materials/une/f-5607 "F.5607") | [1.3243](/materials/material-no/1.3243 "1.3243") | High-speed steels | 0.87–0.95 | 19 | | [F.5611](/materials/une/f-5611 "F.5611") | [1.3249](/materials/material-no/1.3249 "1.3249") | High-speed steels | 0.85–0.92 | 4 | | [F.5613](/materials/une/f-5613 "F.5613") | [1.3243](/materials/material-no/1.3243 "1.3243") | High-speed steels | 0.87–0.95 | 19 | | [F.5613](/materials/une/f-5613 "F.5613") | [1.3246](/materials/material-no/1.3246 "1.3246") | High-speed steels | 1.05–1.15 | 5 | | [F.5615](/materials/une/f-5615 "F.5615") | [1.3247](/materials/material-no/1.3247 "1.3247") | High-speed steels | 1.05–1.15 | 14 | | [F.8211](/materials/une/f-8211 "F.8211") | [1.1165](/materials/material-no/1.1165 "1.1165") | Quenched and tempered steels | 0.25–0.32 | 16 | | [F.8211](/materials/une/f-8211 "F.8211") | [1.1166](/materials/material-no/1.1166 "1.1166") | Others | 0.3–0.37 | 4 | | [F.8212](/materials/une/f-8212 "F.8212") | [1.1167](/materials/material-no/1.1167 "1.1167") | Quenched and tempered steels | 0.32–0.4 | 17 | | [F.8221](/materials/une/f-8221 "F.8221") | [1.7033](/materials/material-no/1.7033 "1.7033") | Quenched and tempered steels | 0.3–0.37 | 18 | | [F.8231](/materials/une/f-8231 "F.8231") | [1.7220](/materials/material-no/1.7220 "1.7220") | Quenched and tempered steels | 0.3–0.37 | 24 | | [F.8232](/materials/une/f-8232 "F.8232") | [1.7225](/materials/material-no/1.7225 "1.7225") | Quenched and tempered steels | 0.38–0.45 | 25 | | [F.8232 -
