DIN / EN · Europe · 2 designations # L175 L175 is a material in the category [High-strength steels](/categories/high-strength-steels "High-strength steels"), held under material number 1.8700. Its recorded composition includes C ≤ 0.21%, Cr ≤ 0.5%, Mn ≤ 0.6%, Ni 0.5% and Cu ≤ 0.6%. We list one designation recorded for this grade, in the standard DIN / EN. Its recorded density is 7.85 g/cm³. - [*Material no.* **1.8700**](/materials/material-no/1.8700 "Material no.: 1.8700") - [*Category* **High-strength steels · 128 grades**](/categories/high-strength-steels "Category: High-strength steels · 128 grades") - *Designations* **2** [Search](/search "Steel grade search")[Inquiry](/inquiry?material=f89cacc2-0409-4078-9522-459cec5d350f&designation=c3610430-2002-478c-ba9d-75e11a92d4d0 "Inquiry")[**Datasheet as PDF** Print-ready A4 document **Generating …** **Download started** **Try again**](/materials/din-en/l175.pdf "Datasheet as PDF") ## If you came for one of these The most-used names for this grade. - [DIN / EN L75 This grade’s own name](/materials/din-en/l75 "DIN / EN L75") ## About High-strength steels High-strength steels are steels designed to carry high loads while resisting deformation. They are used for load-bearing structures, vehicles and machinery where strength, durability and reduced material weight are important. This describes the material class as a whole. Always confirm the individual grade against the standard before ordering. ## Also known as 2 designations · 1 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 Withdrawn designation no longer current — a separate column from the two above, so a name can be same grade and withdrawn at once.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 · 2 - **L175 This grade’s own name** - [L75 This grade’s own name](/materials/din-en/l75 "DIN / EN L75") Every designation on file is listed — no truncation, no “+ n more”. Each one is itself a route that leads back here. ## Chemical composition 8 elements on file · weight % What this alloy is Fe Mn Cu Cr Iron — the balance, never listed by a standard — 97.4 % Mn — 0.6 % Cu — 0.6 % Cr — 0.5 % Traces & impurities · 0.9 % Logarithmic scale, 0.01 % to 100 % — every value here compares directly, decade by decade. | Element | % by weight | |---|---| | C | ≤ 0.21 | | Mn | ≤ 0.6 | | P | 0.03 | | S | 0.03 | | Cr | ≤ 0.5 | | Mo | ≤ 0.15 | | Ni | 0.5 | | Cu | ≤ 0.6 | Carbon Manganese Phosphorus Sulfur Chromium Molybdenum Nickel Copper 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 | ≤0,21 | — | 0.210 | Max | | P | 0,03 | 0.030 | 0.030 | Exact | | S | 0,03 | 0.030 | 0.030 | Exact | | Cr | ≤0,50 | — | 0.500 | Max | | Mn | ≤0,60 | — | 0.600 | Max | | Ni | 0,5 | 0.500 | 0.500 | Exact | | Cu | ≤0,60 | — | 0.600 | Max | | Mo | ≤0,15 | — | 0.150 | Max | 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. ## 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 1.8, a shared category, and a published range for Ni / Mn 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.
