Din 17243 Pdf May 2026

These are non-magnetic and used for the highest temperature ranges (up to 700°C+).

The standard listed several well-known material numbers (Werkstoffnummern), including:

Because many legacy drawings, maintenance manuals, and academic textbooks still reference it. Engineers need the old document for reverse engineering or historical analysis.

Because DIN 17243 has been officially withdrawn. Since the implementation of the European system of technical standards (Eurocodes and European Standards), all national standards (Germany's DIN, France's NF, UK's BS) for spring steels have been replaced by EN 10089: Hot-rolled steels for quenched and tempered springs.

DIN has withdrawn its conflicting standards, and while they allow the use of old copies for reference, they no longer sell the PDF directly. Therefore, no official DIN 17243 PDF is available for purchase from the Beuth Verlag (DIN’s publishing arm). din 17243 pdf

For historical research only, you might find an original scanned DIN 17243 PDF on specialized document archives (e.g., Internet Archive). Warning: Never use an obsolete standard for new product manufacturing – it violates liability laws in the EU and many other regions.

The standard included several well-known steel grades, including but not limited to:

| Old DIN 17243 Grade | Material Number | Type | Modern Equivalent (EN 10089) | |-------------------------|--------------------|----------|----------------------------------| | Ck 67 | 1.1231 | Unalloyed | C66D | | Ck 75 | 1.1248 | Unalloyed | C76D | | 50CrV4 | 1.8159 | Alloyed | 51CrV4 | | 55Cr3 | 1.7176 | Alloyed | 55Cr3 | | 60SiCr7 | 1.7108 | Alloyed | 60SiCr7 | | 51Si7 | 1.5024 | Alloyed | 51Si7 |

These steels were prized for their ability to withstand repeated loading without permanent deformation. The 50CrV4 (1.8159) grade, for instance, became the gold standard for automotive leaf springs and coil springs. These are non-magnetic and used for the highest

Materials in pressure vessels must not become brittle. DIN 17243 specifies impact energy requirements (measured in Joules via Charpy V-notch test) to ensure safety against brittle fracture, often tested at sub-zero temperatures.

For those who still need the actual technical data from the original DIN 17243 PDF, here is a summary of key tables:

| Grade | C | Si | Mn | P | S | Pb | |-------|---|---|----|---|---|----| | 9SMnPb28 | 0.10–0.14 | 0.40 | 0.90–1.20 | 0.11 | 0.27–0.33 | 0.15–0.35 | often tested at sub-zero temperatures.
