GOST · 3,544 grades # GOST steel grades — 3544 designations — Page 71 Every grade designated under GOST, with the identifying and comparative data we hold for each. 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 | C% by weight | |---|---| | [ЭИ993](/materials/gost/ei993 "ЭИ993") | 0.15–0.22 | | [ЭЛ 107](/materials/gost/el-107 "ЭЛ 107") | 0.35–0.45 | | [ЭП-111](/materials/gost/ep-111 "ЭП-111") | 0.05–0.15 | | [ЭП-307](/materials/gost/ep-307 "ЭП-307") | ≤ 0.08 | | [ЭП-367](/materials/gost/ep-367 "ЭП-367") | ≤ 0.08 | | [ЭП-377](/materials/gost/ep-377 "ЭП-377") | 0.05–0.1 | | [ЭП-389](/materials/gost/ep-389 "ЭП-389") | ≤ 0.1 | | [ЭП-439](/materials/gost/ep-439 "ЭП-439") | 0.13–0.17 | | [ЭП-516](/materials/gost/ep-516 "ЭП-516") | ≤ 0.03 | | [ЭП-75](/materials/gost/ep-75 "ЭП-75") | 0.72–0.8 | | [ЭП-87](/materials/gost/ep-87 "ЭП-87") | ≤ 0.08 | | [ЭП-89](/materials/gost/ep-89 "ЭП-89") | ≤ 0.08 | | [ЭП164](/materials/gost/ep164 "ЭП164") | ≤ 0.08 | | [ЭП182](/materials/gost/ep182 "ЭП182") | 0.17–0.24 | | [ЭП222](/materials/gost/ep222 "ЭП222") | ≤ 0.07 | | [ЭП288](/materials/gost/ep288 "ЭП288") | 0.05–0.15 | | [ЭП291](/materials/gost/ep291 "ЭП291") | 0.15–0.21 | | [ЭП303](/materials/gost/ep303 "ЭП303") | 0.48–0.58 | | [ЭП303Б](/materials/gost/ep303b "ЭП303Б") | 0.5–0.6 | | [ЭП33](/materials/gost/ep33 "ЭП33") | ≤ 0.1 | | [ЭП410](/materials/gost/ep410 "ЭП410") | ≤ 0.17 | | [ЭП410-Ш](/materials/gost/ep410-sh "ЭП410-Ш") | ≤ 0.17 | | [ЭП410У](/materials/gost/ep410u "ЭП410У") | ≤ 0.08 | | [ЭП410У-ВД](/materials/gost/ep410u-vd "ЭП410У-ВД") | ≤ 0.08 | | [ЭП410У-Ш](/materials/gost/ep410u-sh "ЭП410У-Ш") | ≤ 0.08 | | [ЭП428](/materials/gost/ep428 "ЭП428") | 0.17–0.23 | | [ЭП430](/materials/gost/ep430 "ЭП430") | 0.1–0.18 | | [ЭП44](/materials/gost/ep44 "ЭП44") | 0.18–0.25 | | [ЭП450](/materials/gost/ep450 "ЭП450") | 0.1–0.15 | | [ЭП450-Ш](/materials/gost/ep450-sh "ЭП450-Ш") | 0.1–0.15 | | [ЭП47](/materials/gost/ep47 "ЭП47") | ≤ 0.1 | | [ЭП48](/materials/gost/ep48 "ЭП48") | 0.4–0.5 | | [ЭП503](/materials/gost/ep503 "ЭП503") | 0.07–0.12 | | [ЭП505](/materials/gost/ep505 "ЭП505") | 0.07–0.12 | | [ЭП53](/materials/gost/ep53 "ЭП53") | ≤ 0.08 | | [ЭП54](/materials/gost/ep54 "ЭП54") | ≤ 0.05 | | [ЭП550](/materials/gost/ep550 "ЭП550") | ≤ 0.03 | | [ЭП56](/materials/gost/ep56 "ЭП56") | 0.08–0.12 | | [ЭП569](/materials/gost/ep569 "ЭП569") | 0.5–0.6 | | [ЭП572](/materials/gost/ep572 "ЭП572") | 0.35–0.42 | | [ЭП752](/materials/gost/ep752 "ЭП752") | 0.1–0.15 | | [ЭП761](/materials/gost/ep761 "ЭП761") | 0.8–0.9 | | [ЭП788](/materials/gost/ep788 "ЭП788") | 0.55–0.62 | | [ЭП864](/materials/gost/ep864 "ЭП864") | ≤ 0.03 | **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.
