Material number · Europe · 3 designations # 1.9301 1.9301 is the material number of the grade also listed as SAE 1010. 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.* **1.9301**** - [*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=1e8cea89-c14e-4e22-9f15-2437d8aa6d6d "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/material-no/1.9301.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN SAE 1010 This grade’s own name · 2 grades on that route](/materials/din-en/sae1010 "DIN / EN SAE 1010") - [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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once. DIN / EN Europe · 1 - [SAE 1010 This grade’s own name](/materials/din-en/sae1010 "DIN / EN SAE 1010") UNS United States · 1 - [G10100 This grade’s own name](/materials/uns/g10100 "UNS G10100") AISI / SAE United States · 1 - [1010 This grade’s own name](/materials/aisi-sae/1010 "AISI / SAE 1010") Every designation on file is listed — no truncation, no “+ n more”. Each one is itself a route that leads back here. ## Chemical composition 4 elements on file · weight % What this alloy is Fe Mn C S Iron — the balance, never listed by a standard — 99.4 % Mn — 0.4 % C — 0.1 % S — 0.1 % Traces & impurities · 0 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | 0.08–0.13 | | Mn | 0.3–0.6 | | P | 0.03 | | S | 0.05 — Unusual | Carbon 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 | 0,08-0,13 | 0.080 | 0.130 | Range | | P | 0,03 | 0.030 | 0.030 | Exact | | S | 0,05 | 0.050 | 0.050 | Exact | | Mn | 0,30-0,60 | 0.300 | 0.600 | 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: Si, 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. ## Looking for this grade under another name?
