Material number · Europe · 10 designations # 1.1183 1.1183 is the material number of the grade also listed as C35G. It is a material in the category Steels for surface hardening. We list 10 designations recorded for this grade, in the standards DIN / EN, AISI / SAE, BS, AFNOR, JIS, GB, UNI and SS. - ***Material no.* **1.1183**** - [*Category* **Steels for surface hardening · 13 grades**](/categories/steels-for-surface-hardening "Category: Steels for surface hardening · 13 grades") - *Designations* **10** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=77120fb4-af6d-412a-a8e5-c8127acd6739 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/material-no/1.1183.pdf "Datasheet as PDF") ## About Steels for surface hardening Steels for surface hardening are steels designed to develop a hard, wear-resistant surface while retaining a tougher interior. They are used for gears, shafts and other machine parts where resistance to surface wear is needed together with resistance to impact and bending. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 10 designations · 8 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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 Mn C Si Iron — the balance, never listed by a standard — 98.7 % Mn — 0.7 % C — 0.4 % 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 | 0.33–0.39 | | Si | 0.15–0.35 | | Mn | 0.5–0.8 | | P | 0.025 | | S | 0.035 | 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 | 0,33-0,39 | 0.330 | 0.390 | Range | | Si | 0,15-0,35 | 0.150 | 0.350 | Range | | P | 0,025 | 0.025 | 0.025 | Exact | | S | 0,035 | 0.035 | 0.035 | Exact | | Mn | 0,50-0,80 | 0.500 | 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. ## Heat treatment Supply condition - Normalizing and Quenching and Tempering Test specimen size d=25 Conditions the standard permits on delivery. No temperature or medium is published for these, so no order and no alternation is implied.

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