GOST · 3,544 grades # GOST steel grades — 3544 designations — Page 64 Every grade designated under GOST, 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 3544 designations | Grade | Material no. | Category | C% by weight | Also in other standards | |---|---|---|---|---| | [Р12М3К5Ф2-МП](/materials/gost/r12m3k5f2-mp "Р12М3К5Ф2-МП") | — | — | 1.05–1.15 | — | | [Р12МФ5-МП](/materials/gost/r12mf5-mp "Р12МФ5-МП") | [EN-JS1102](/materials/material-no/en-js1102 "EN-JS1102") | Others | — | 21 | | [Р12МФ5К5](/materials/gost/r12mf5k5 "Р12МФ5К5") | [1.3202](/materials/material-no/1.3202 "1.3202") | High-speed steels | 1.3–1.45 | 12 | | [Р12Ф3](/materials/gost/r12f3 "Р12Ф3") | [1.3318](/materials/material-no/1.3318 "1.3318") | High-speed steels | 0.9–1 | 4 | | [Р14Ф4](/materials/gost/r14f4 "Р14Ф4") | — | — | 1.2–1.3 | — | | [Р18](/materials/bds/r18 "Р18") | [1.3355](/materials/material-no/1.3355 "1.3355") | High-speed steels | 0.73–0.83 | 22 | | [Р18К5Ф2](/materials/gost/r18k5f2 "Р18К5Ф2") | [1.3255](/materials/material-no/1.3255 "1.3255") | High-speed steels | 0.75–0.83 | 14 | | [Р18Ф2](/materials/gost/r18f2 "Р18Ф2") | — | — | 0.85–0.95 | — | | [Р18Ф2К5](/materials/gost/r18f2k5 "Р18Ф2К5") | — | — | 0.85–0.95 | — | | [Р2АМ9К5](/materials/gost/r2am9k5 "Р2АМ9К5") | [1.3247](/materials/material-no/1.3247 "1.3247") | High-speed steels | 1.05–1.15 | 14 | | [Р6АМ5Ф3](/materials/gost/r6am5f3 "Р6АМ5Ф3") | — | — | 0.95–1.05 | — | | [Р6М3](/materials/gost/r6m3 "Р6М3") | — | — | 0.85–0.95 | — | | [Р6М4Ф2Л](/materials/gost/r6m4f2l "Р6М4Ф2Л") | — | — | 0.85–0.95 | — | | [Р6М5](/materials/bds/r6m5 "Р6М5") | [1.3343](/materials/material-no/1.3343 "1.3343") | High-speed steels | 0.86–0.94 | 19 | | [Р6М5К5](/materials/bds/r6m5k5 "Р6М5К5") | [1.3243](/materials/material-no/1.3243 "1.3243") | High-speed steels | 0.87–0.95 | 19 | | [Р6М5Л](/materials/gost/r6m5l "Р6М5Л") | [1.0612](/materials/material-no/1.0612 "1.0612") | Others | 0.63–0.68 | 12 | | [Р6М5Ф3](/materials/gost/r6m5f3 "Р6М5Ф3") | [1.3344](/materials/material-no/1.3344 "1.3344") | High-speed steels | 1.15–1.25 | 8 | | [Р7М2Ф6-МП](/materials/gost/r7m2f6-mp "Р7М2Ф6-МП") | — | — | 3.2–3.6 | — | | [Р9](/materials/gost/r9 "Р9") | — | — | 0.85–0.95 | — | | [Р9К10](/materials/gost/r9k10 "Р9К10") | — | — | 0.9–1 | — | | [Р9К5](/materials/gost/r9k5 "Р9К5") | — | — | 0.9–1 | — | | [Р9М4К8](/materials/gost/r9m4k8 "Р9М4К8") | [1.3207](/materials/material-no/1.3207 "1.3207") | High-speed steels | 1.2–1.35 | 14 | | [Р9Ф5](/materials/gost/r9f5 "Р9Ф5") | — | — | 1.4–1.5 | — | | [С235](/materials/gost/s235 "С235") | [1.0035](/materials/material-no/1.0035 "1.0035") | Unalloyed structural steels | — | 22 | | [С245](/materials/gost/s245 "С245") | [1.0038](/materials/material-no/1.0038 "1.0038") | Unalloyed structural steels | ≤ 0.17 | 26 | | [С255](/materials/gost/s255 "С255") | [1.0036](/materials/material-no/1.0036 "1.0036") | Unalloyed structural steels | ≤ 0.17 | 20 | | [С275](/materials/gost/s275 "С275") | — | — | ≤ 0.22 | — | | [С285](/materials/gost/s285 "С285") | [1.0050](/materials/material-no/1.0050 "1.0050") | Unalloyed structural steels | — | 23 | | [С285](/materials/gost/s285 "С285") | [1.0050](/materials/material-no/1.0050 "1.0050") | Unalloyed structural steels | — | 23 | | [С345](/materials/gost/s345 "С345") | [1.0570](/materials/material-no/1.0570 "1.0570") | Unalloyed structural steels | ≤ 0.2 | 22 | | [С345](/materials/gost/s345 "С345") | [1.0570](/materials/material-no/1.0570 "1.0570") | Unalloyed structural steels | ≤ 0.2 | 20 | | [С345Д](/materials/gost/s345d "С345Д") | — | — | ≤ 0.15 | — | | [С345К](/materials/gost/s345k "С345К") | — | — | ≤ 0.12 | — | | [С345Т](/materials/gost/s345t "С345Т") | — | — | ≤ 0.22 | — | | [С375](/materials/gost/s375 "С375") | [1.0070](/materials/material-no/1.0070 "1.0070") | Unalloyed structural steels | — | 16 | | [С375Д](/materials/gost/s375d "С375Д") | — | — | ≤ 0.15 | — | | [С375Т](/materials/gost/s375t "С375Т") | — | — | ≤ 0.2 | — | | [С390](/materials/gost/s390 "С390") | — | — | ≤ 0.18 | — | | [С390Д](/materials/gost/s390d "С390Д") | — | — | ≤ 0.18 | — | | [С390К](/materials/gost/s390k "С390К") | — | — | ≤ 0.18 | — | | [С390Т](/materials/gost/s390t "С390Т") | — | — | ≤ 0.15 | — | | [С440](/materials/gost/s440 "С440") | — | — | ≤ 0.2 | — | | [С440Д](/materials/gost/s440d "С440Д") | — | — | ≤ 0.2 | — | | [С590](/materials/gost/s590 "С590") | — | — | ≤ 0.15 | — | | [С590К](/materials/gost/s590k "С590К") | — | — | ≤ 0.14 | — | | [С590КШ](/materials/gost/s590ksh "С590КШ") | — | — | ≤ 0.14 | — | | [Св-01Х19Н9](/materials/gost/sv-01kh19n9 "Св-01Х19Н9") | — | — | ≤ 0.03 | — | | [Св-01Х23Н28М3Д3Т](/materials/gost/sv-01kh23n28m3d3t "Св-01Х23Н28М3Д3Т") | — | — | ≤ 0.03 | — | | [Св-04Х19Н11М3](/materials/gost/sv-04kh19n11m3 "Св-04Х19Н11М3") | — | — | ≤ 0.06 | — | | [Св-04Х19Н9](/materials/gost/sv-04kh19n9 "Св-04Х19Н9") | — | — | ≤ 0.06 | — | **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;
