GOST steel grades — 3544 designations — Page 51
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. Unless marked, every name here is an indicative cross-reference, not an asserted identity — the grades are close, not interchangeable. 17 of 50 rows differ and carry a “This grade’s own name” mark.

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Withdrawn — designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.
