17243 Pdf: Din
DIN 17243 is a withdrawn German standard that specifies the technical delivery conditions for weldable heat-resisting steel forgings and rolled or forged steel bars . It is widely used in high-temperature applications, such as steam boiler plants, pressure vessels, and pipework . Key Technical Details
Material Types: The standard covers forgeable and weldable steels designed for elevated temperatures . A common grade associated with this standard is C22.8 (Material Number 1.0460), often used for C22.8 steel flanges .
Scope of Application: It applies to products like collectors, seamless rolled rings, and container courses with pressed-on bottoms .
Replacement: This standard has largely been succeeded by European standards, such as EN 10222-2 (for steel forgings for pressure purposes) . Critical Specifications for DIN 17243 (Grade C22.8 Example) Typical Requirement Tensile Strength 485 MPa (minimum) Yield Strength 250 MPa (minimum) Elongation 30% (minimum) Hardness 187 HB (maximum) Accessing the PDF din 17243 pdf

Title: Hot-rolled steels for quenched and tempered springs – Technical delivery conditions.
This European standard has table of equivalence that maps almost every grade from the old DIN 17243 to the new EN designation. For example:
- Old: 50CrV4 (DIN 17243) → New: 51CrV4 (EN 10089)
You can purchase the official DIN EN 10089 PDF directly from Beuth Verlag or other national standards bodies. This is the legally binding document for all spring steel deliveries in Germany and the EU today.
