GOST · Russia / CIS · 31 designations # АS45G2 АS45G2 is a designation in GOST for the material held under material number 1.0912, also listed as 46Mn7. It is a material in the category Others. We list 31 designations recorded for this grade, in the standards DIN / EN, UNS, AISI / SAE, BS, AFNOR, JIS, GB, GOST, UNI, ČSN, PN and BDS. - [*Material no.* **1.0912**](/materials/material-no/1.0912 "Material no.: 1.0912") - [*Category* **Others · 1754 grades**](/categories/others "Category: Others · 1754 grades") - *Designations* **31** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=8b45c527-33b4-4fe5-b1e0-538aa5ba5a29&designation=df3acbf4-87c7-4e18-9ced-9364a9c2a369 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gost/as45g2.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN 46Mn7 This grade’s own name](/materials/din-en/46mn7 "DIN / EN 46Mn7") - [UNS G13450 This grade’s own name](/materials/uns/g13450 "UNS G13450") - [AISI / SAE 1345 This grade’s own name · 2 grades on that route](/materials/aisi-sae/1345 "AISI / SAE 1345") ## About Others These are miscellaneous metallic alloys that do not fit a more specific material family and may be based on iron, nickel, cobalt, copper or other alloy systems. They are selected for applications requiring particular combinations of strength, hardness, toughness, wear resistance or resistance to demanding service conditions. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 31 designations · 12 standards · nothing hidden 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Flake sensitivity susceptible As published: predisposed Temper brittleness not susceptible As published: not predisposed An absent property means we hold no value for it — it is left out rather than estimated, interpolated from a neighbouring grade, or filled from a handbook.

Values are never merged across conditions or across sources, never averaged, and never interpolated between two rows. An em dash means no value on file — never zero. Figures are converted to the unit in the column header; the source’s own wording is kept and shown where the two differ. ## Heat treatment Supply condition - Annealing - Normalizing and Tempering d≤100 - Quenching and Tempering d=25 - Annealing and Tempering and Normalizing Supply condition - Spheroidize annealing Plate and Strip Conditions the standard permits on delivery.

These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
