GOST · 3,544 grades # GOST steel grades — 3544 designations — Page 41 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. Unless marked, every name here is an indicative cross-reference, not an asserted identity — the grades are close, not interchangeable. 19 of 50 rows differ and carry a “This grade’s own name” mark. ## Also known as 3544 designations | Grade | C% by weight | |---|---| | [68ГА](/materials/gost/68ga "68ГА") | 0.65–0.73 | | [6ChV2S](/materials/gost/6chv2s "6ChV2S") | 0.55–0.65 | | [6ChV2S](/materials/gost/6chv2s "6ChV2S") | 0.4–0.5 | | [6G2АF](/materials/gost/6g2af "6G2АF") This grade’s own name | 0.14–0.2 | | [6HW2S](/materials/gost/6hw2s "6HW2S") | 0.55–0.65 | | [6KH3MFS](/materials/gost/6kh3mfs "6KH3MFS") This grade’s own name | 0.55–0.62 | | [6KH4M2FS](/materials/gost/6kh4m2fs "6KH4M2FS") | 0.85–0.95 | | [6KH6V3MFS](/materials/gost/6kh6v3mfs "6KH6V3MFS") This grade’s own name | 0.5–0.6 | | [6KHS](/materials/gost/6khs "6KHS") | — | | [6KHV2S](/materials/gost/6khv2s "6KHV2S") This grade’s own name | 0.55–0.65 | | [6KhV2S](/materials/gost/6khv2s "6KhV2S") | 0.55–0.65 | | [6KHVG](/materials/gost/6khvg "6KHVG") | — | | [6XB2C](/materials/gost/6xb2c "6XB2C") | 0.55–0.65 | | [6XB2C](/materials/gost/6xb2c "6XB2C") | 0.4–0.5 | | [6Г2АФ](/materials/gost/6g2af "6Г2АФ") | 0.14–0.2 | | [6Х3МФС](/materials/gost/6kh3mfs "6Х3МФС") | 0.55–0.62 | | [6Х6В3МФС](/materials/gost/6kh6v3mfs "6Х6В3МФС") | 0.5–0.6 | | [6ХВ2С](/materials/gost/6khv2s "6ХВ2С") | 0.55–0.65 | | [70](/materials/gb/70 "70") | 0.68–0.73 | | [70](/materials/gb/70 "70") | 0.65–0.73 | | [70G](/materials/gost/70g "70G") This grade’s own name | 0.67–0.75 | | [70G2](/materials/gost/70g2 "70G2") This grade’s own name | 0.65–0.75 | | [70GL](/materials/gost/70gl "70GL") This grade’s own name | 0.65–0.8 | | [70Kh2GL](/materials/gost/70kh2gl "70Kh2GL") This grade’s own name | 0.6–0.75 | | [70KhGFA](/materials/gost/70khgfa "70KhGFA") This grade’s own name | 0.065–0.72 | | [70S2KHА](/materials/gost/70s2kha "70S2KHА") This grade’s own name | 0.65–0.75 | | [70S3А](/materials/gost/70s3a "70S3А") This grade’s own name | 0.66–0.74 | | [70Г](/materials/gost/70g "70Г") | 0.67–0.75 | | [70Г2](/materials/gost/70g2 "70Г2") | 0.65–0.75 | | [70ГЛ](/materials/gost/70gl "70ГЛ") | 0.65–0.8 | | [70С2ХА](/materials/gost/70s2kha "70С2ХА") | 0.65–0.75 | | [70С3А](/materials/gost/70s3a "70С3А") | 0.66–0.74 | | [70Х2ГЛ](/materials/gost/70kh2gl "70Х2ГЛ") | 0.6–0.75 | | [70ХГФА](/materials/gost/70khgfa "70ХГФА") | 0.065–0.72 | | [75](/materials/gost/75 "75") This grade’s own name | 0.72–0.8 | | [75](/materials/gost/75 "75") | 0.73–0.78 | | [75](/materials/gost/75 "75") | 0.7–0.8 | | [75](/materials/gost/75 "75") | 0.7–0.8 | | [75](/materials/gost/75 "75") | 0.7–0.8 | | [75KHM](/materials/gost/75khm "75KHM") This grade’s own name | 0.7–0.8 | | [75KHMF](/materials/gost/75khmf "75KHMF") This grade’s own name | 0.7–0.8 | | [75KhNMFL](/materials/gost/75khnmfl "75KhNMFL") This grade’s own name | 0.7–0.85 | | [75KHSMF](/materials/gost/75khsmf "75KHSMF") This grade’s own name | 0.72–0.8 | | [75ХМ](/materials/gost/75khm "75ХМ") | 0.7–0.8 | | [75ХМФ](/materials/gost/75khmf "75ХМФ") | 0.7–0.8 | | [75ХНМФЛ](/materials/gost/75khnmfl "75ХНМФЛ") | 0.7–0.85 | | [75ХСМФ](/materials/gost/75khsmf "75ХСМФ") | 0.72–0.8 | | [76](/materials/gost/76 "76") This grade’s own name | 0.71–0.84 | | [76F](/materials/gost/76f "76F") This grade’s own name | 0.71–0.87 | | [76T](/materials/gost/76t "76T") This grade’s own name | 0.71–0.84 | **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.
