GOST · Russia / CIS · 33 designations # Sv-10KhMFT Sv-10KhMFT is a designation in GOST for the material held under material number 1.0310, also listed as C10D. It is a material in the category Unalloyed structural steels. We list 33 designations recorded for this grade, in the standards DIN / EN, UNS, AISI / SAE, JIS, GB and GOST. - [*Material no.* **1.0310**](/materials/material-no/1.0310 "Material no.: 1.0310") - [*Category* **Unalloyed structural steels · 452 grades**](/categories/unalloyed-structural-steels "Category: Unalloyed structural steels · 452 grades") - *Designations* **33** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=c9023171-8676-4cdb-9eb7-ccee14ad9f0a&designation=419e1795-57c6-4b8c-a019-7bd4a4e24a6f "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gost/sv-10khmft.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN C10D This grade’s own name](/materials/din-en/c10d "DIN / EN C10D") - [UNS G10100 This grade’s own name · 8 grades on that route](/materials/uns/g10100 "UNS G10100") - [AISI / SAE 1010 This grade’s own name · 10 grades on that route](/materials/aisi-sae/1010 "AISI / SAE 1010") - [GB 10 This grade’s own name · 3 grades on that route](/materials/gb/10 "GB 10") ## About Unalloyed structural steels Unalloyed structural steels include all low-carbon steels in which the iron companions do not exceed specified minimum values. The yield strength, formability and weldability are the decisive factors for their use. They are soft, pliable, tough and stretchy, but cannot be hardened by heat treatment. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 33 designations · 6 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.

Elements not listed have no value on file — they are omitted, never inferred. ## Predicted transformation temperatures computed from composition · °C Predicted Ae3 831 °C Predicted Ae1 722 °C Predicted Acm 363 °C Predicted Bs 596 °C These four temperatures are a CALCULATION from this grade's own composition, using the published Li, Niebuhr, Meekisho & Atteridge (1998) model — never a measurement, and computed from the UPPER BOUND of each element's specified range, not a mid-range figure. Where this grade also has a measured transformation point (Ac1, Ac3, Ar1, Ar3) on file, it is shown separately, in Physical & mechanical properties, and is never replaced by the predicted figures here — Ae (predicted, equilibrium) and Ac/Ar (measured, on heating or cooling) are different physical quantities and can differ by tens of degrees; a mismatch between the two is not an error in either. ## Physical & mechanical properties Density 7,85 g/cm³ Exact Transformation point Ac1 724 °C Exact Transformation point Ac3 876 °C Exact · Ac3(Acm) Transformation point Ar3 850 °C Exact · Ar3(Arcm) Transformation point Ar1 682 °C Exact Weldability readily weldable As published: without limitations. Flake sensitivity not susceptible As published: not 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. It does not mean the property is undefined for the material. ## Properties by condition 5 conditions · 94 values By delivery state**no delivery state stated** source `splav` | Delivery state | Rm N/mm² | Re N/mm² | A5% | Z% | KCU kJ/m² | HB | |---|---|---|---|---|---|---| | Pipe hot strain, GOST 550-75 | 353 | 216 | 25 | 50 | 780 | — | | Pipe, GOST 8731-87 | 353 | 216 | 24 | — | — | — | | Pipe, GOST 10705-80 | 314 | 196 | 25 | — | — | — | | Rolled stock cold-worked , GOST 1050-88 | 410 | — | 8 | 50 | — | — | | Rolled stock annealed , GOST 1050-88 | 290 | — | 26 | 55 | — | — | | Rolled stock, GOST 10702-78 | 390 | — | 8 | 50 | — | — | | (cold-drawn, cold-worked) , GOST 1050-88 | — | — | — | — | — | 187 | | (hot-rolled) , GOST 1050-88 | — | — | — | — | — | 143 | | Sheet GOST 4041-71 | — | — | — | — | — | 117 | | Pipe GOST 8731-87 | — | — | — | — | — | 137 | | Pipe GOST 550-75 | — | — | — | — | — | 137 | | Bar GOST 10702-78 | — | — | — | — | — | 115 | By dimension**no delivery state stated** source `caishuku` | Wall thickness mm | Rm N/mm² | A% | |---|---|---| | ≤ 16 | 335 – 475 | ≥ 24 | | ≥ 16 | 335 – 475 | ≥ 24 | By dimension**no delivery state stated** source `splav` | Dimension mm | Rm N/mm² | A5% | |---|---|---| | 4 - 14 | 290 – 420 | 32 | By dimension**Normalizing** source `splav` | Dimension mm | Rm N/mm² | Re N/mm² | A5% | Z% | |---|---|---|---|---| | to 80 | 330 | 205 | 31 | 55 | At temperature**no delivery state stated** source `splav` | Temperature °C | Density g/cm³ | Elastic modulus GPa | Thermal expansion coefficient 10^-6/K | Thermal conductivity W/(m·K) | Specific heat capacity J/(kg·K) | Electrical resistivity nΩ·m | |---|---|---|---|---|---|---| | 20 | 7.856 | 210 | — | — | — | 140 | | 100 | 7.832 | 203 | 12.4 | 57 | 494 | 190 | | 200 | 7.8 | 199 | 13.2 | 53 | 532 | 263 | | 300 | 7.765 | 190 | 13.9 | 49.6 | 565 | 352 | | 400 | 7.73 | 182 | 14.5 | 45 | 611 | 458 | | 500 | 7.692 | 172 | 14.85 | 39.9 | 682 | 584 | | 600 | 7.653 | 160 | 15.1 | 35.7 | 770 | 734 | | 700 | 7.613 | — | 15.2 | 32 | 857 | 905 | | 800 | 7.582 | — | 12.05 | 29 | 875 | 1081 | | 900 | 7.594 | — | 14.08 | 27 | 795 | 1130 | | 1000 | — | — | 12.6 | — | 666 | — | | 1100 | — | — | 14.4 | — | 668 | — | 2 further values are held for this grade under a condition the source did not name — a bound with no quantity attached. They are withheld rather than shown against a guessed condition. Every figure holds only for the condition on its own row. 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. ## Similar grades — and why Selection rule, stated so you can disagree with it: same number class 1.0, a shared category, and a published range for Mn / Si that overlaps this grade’s. These are neighbours in composition space — they are not equivalents, and none is claimed to be interchangeable with this grade.
