Material number · Europe · 3 designations # 1.1114 1.1114 is the material number of the grade also listed as C10D2. It is a material in the category Case hardening steels. We list 3 designations recorded for this grade, in the standards DIN / EN, UNS and AISI / SAE. - ***Material no.* **1.1114**** - [*Category* **Case hardening steels · 60 grades**](/categories/case-hardening-steels "Category: Case hardening steels · 60 grades") - *Designations* **3** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=ac736937-deea-4c50-90d3-be9dea8e5e97 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/material-no/1.1114.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN C10D2 This grade’s own name](/materials/din-en/c10d2 "DIN / EN C10D2") - [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") ## About Case hardening steels Case hardening steels are steels designed to develop a hard, wear-resistant surface while retaining a tough and ductile core. They are used for components such as gears, shafts and other machine parts exposed to contact wear and cyclic loading. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 3 designations · 3 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.

Elements not listed have no value on file — they are omitted, never inferred. ## Predicted transformation temperatures computed from composition · °C Predicted Ae3 837 °C Predicted Ae1 723 °C Predicted Acm 350 °C Predicted Bs 606 °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 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 1.1, 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.
