SRPS · Serbia · 14 designations # Č.1832 Č.1832 is a designation in SRPS for the material held under material number 1.0605, also listed as C75. It is a material in the category Spring steels. We list 14 designations recorded for this grade, in the standards DIN / EN, UNS, AISI / SAE, BS, AFNOR, JIS, GOST, ČSN, STN, PN, SRPS and STAS. - [*Material no.* **1.0605**](/materials/material-no/1.0605 "Material no.: 1.0605") - [*Category* **Spring steels · 52 grades**](/categories/spring-steels "Category: Spring steels · 52 grades") - *Designations* **14** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=11495e98-4592-4d10-85d8-d54ef54f9281&designation=8586de55-40bd-4119-bce7-bd6b9349985b "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/srps/c-1832.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN C75 This grade’s own name](/materials/din-en/c75 "DIN / EN C75") - [UNS G10740 This grade’s own name · 6 grades on that route](/materials/uns/g10740 "UNS G10740") - [AISI / SAE 1074 This grade’s own name · 7 grades on that route](/materials/aisi-sae/1074 "AISI / SAE 1074") ## About Spring steels Spring steels are alloy steels designed to store and release elastic energy repeatedly without permanent deformation. They are characterised by a combination of strength, hardness and resilience, making them suitable for springs, clips, washers and other components subjected to repeated flexing or shock. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 14 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Each one is itself a route that leads back here. ## Chemical composition 5 elements on file · weight % What this alloy is Fe C Mn Si Iron — the balance, never listed by a standard — 98.2 % C — 0.8 % Mn — 0.7 % Si — 0.3 % Traces & impurities · 0.1 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.7–0.8 | | Si | 0.15–0.35 | | Mn | 0.6–0.8 | | P | 0.045 | | S | 0.045 | Carbon Silicon Manganese Phosphorus Sulfur 0.01 % 0.1 % 1 % 10 % 100 % The scale is logarithmic, not the element’s raw share of the alloy — the only honest way to fit 0.01 % and 100 % in one picture, and it means every value here can be compared with every other. | Element | As published source text, verbatim | Min% by weight | Max% by weight | Bound | |---|---|---|---|---| | C | 0,70-0,80 | 0.700 | 0.800 | Range | | Si | 0,15-0,35 | 0.150 | 0.350 | Range | | P | 0,045 | 0.045 | 0.045 | Exact | | S | 0,045 | 0.045 | 0.045 | Exact | | Mn | 0,60-0,80 | 0.600 | 0.800 | Range | The published column is the source string byte-for-byte, decimal comma and all; Min and Max are the parsed bounds. Elements not listed have no value on file — they are omitted, never inferred. ## Predicted transformation temperatures Not enough recorded composition to predict a transformation temperature for this grade — missing: Ni, Cr, Mo. ## Physical & mechanical properties Density 7,85 g/cm³ Exact 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. ## 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.
