GOST · Russia / CIS · 80 designations # ВКЛ-1 ВКЛ-1 is a designation in GOST for the material held under material number 1.0035, also listed as S185. It is a material in the category Unalloyed structural steels. We list 80 designations recorded for this grade, in the standards DIN / EN, AISI / SAE, ASTM, BS, AFNOR, UNE, ISO, JIS, NP, GB, GOST, UNI, SS, ČSN, STN, PN, MSZ, STAS, BDS, ÖNORM, NBN, SFS and KS. - [*Material no.* **1.0035**](/materials/material-no/1.0035 "Material no.: 1.0035") - [*Category* **Unalloyed structural steels · 452 grades**](/categories/unalloyed-structural-steels "Category: Unalloyed structural steels · 452 grades") - *Designations* **80** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=f0d63218-dacb-4c74-b2b0-266b545c972d&designation=d4469bc4-fa20-48f9-a0ba-2f2726b3df24 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/gost/vkl-1.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN S185 This grade’s own name](/materials/din-en/s185 "DIN / EN S185") - [KS SS330 This grade’s own name · 2 grades on that route](/materials/ks/ss330 "KS SS330") ## 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 80 designations · 23 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once. Superseded by the current name this withdrawn designation was replaced by — the same grade under its present designation, the one to order by today.

It does not mean the property is undefined for the material. ## Properties by condition 4 conditions · 27 values By thickness**flat and long products** source `steelnumber` | Thickness mm | ReH N/mm² | Rm N/mm² | |---|---|---| | ≤ 3 | — | 310 – 540 | | 3 – 100 | — | 290 – 510 | | ≤ 16 | 185 | — | | 16 – 40 | 175 | — | | 40 – 63 | 175 | — | | 63 – 80 | 175 | — | | 80 – 100 | 175 | — | | 100 – 150 | 165 | 280 – 500 | | 150 – 250 | — | 270 – 490 | | 150 – 200 | 155 | — | By thickness**no delivery state stated** source `steelnumber` | Thickness mm | A80% · Lo = 80 mm | A% · Lo = 5,65 √So | |---|---|---| | ≤ 1 | 10 | — | | 1 – 1.5 | 11 | — | | 1.5 – 2 | 12 | — | | 2 – 2.5 | 13 | — | | 2.5 – 3 | 14 | — | | 3 – 40 | — | 18 | | 40 – 63 | — | 17 | | 63 – 100 | — | 16 | | 100 – 150 | — | 15 | | 150 – 250 | — | 15 | By delivery state**no delivery state stated** source `splav` | Delivery state | Rm N/mm² | Re N/mm² | A5% | Z% | |---|---|---|---|---| | Rolled stock, GOST 535-2005 | 305 – 390 | 165 – 195 | 32 – 35 | — | | Wire rods , GOST 30136-95 | 420 – 470 | — | — | 66 – 68 | At temperature**no delivery state stated** source `splav` | Temperature °C | Density g/cm³ | |---|---| | 20 | 7.85 | Every figure holds only for the condition on its own row.
