Searching for a DIN 17243 PDF is understandable for maintaining old equipment, but don’t use it for new designs or compliance. Get the EN 10277 or EN 10087 standard instead. If you still want the DIN PDF, buy it from DIN Media or accept the risks of free scans.

DIN 17243 is a withdrawn German standard that specifies the technical delivery conditions for weldable heat-resisting steel forgings and rolled or forged steel bars .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
Because this is a withdrawn historical standard, full-text PDFs are typically found through: din 17243 pdf
Official Portals: You can find the document history and purchase the archived draft at DIN Media .
Technical Libraries: Platforms like Scribd host scanned copies of the technical delivery conditions for reference .
Material Datasheets: Many manufacturers provide extracted data, such as the C 22.8 Material Datasheet from Applus+ Laboratories . DIN 17243 - 1987-01
DIN 17243 is a historical German technical standard titled "Weldable heat-resisting steel forgings and rolled or forged steel bars". It defines the delivery conditions and technical requirements for materials used in high-temperature environments, such as power plant components and pressure vessels. Key Technical Overview
This standard applies primarily to steel products designed to withstand high operational temperatures while maintaining weldability.
Scope: Covers forgings, hot pressed parts, and rolled or forged steel bars. Searching for a DIN 17243 PDF is understandable
Applications: Essential for the manufacturing of steam boiler plants, pipework, and pressure vessels.
Properties: Includes technical delivery conditions for mechanical strength at elevated temperatures, creep limit, and creep rupture stress. Common Material Grades
Historically, several well-known steel grades were categorized under DIN 17243, including:
C22.8 (1.0460): A common carbon steel often used for flanges.
X20CrMoV 121 (1.4922): A high-alloy heat-resisting steel for critical applications.
18CrMo4 (1.7243): Used for advanced parts like gears and shafts operating under 250°C. Status and Replacements Would you like a free cross-reference table from
It is important to note that DIN 17243 has been withdrawn and superseded by European (EN) standards as part of technical harmonization. Standard Type Current Replacement / Successor Steel Forgings DIN EN 10222-2 (Steel forgings for pressure purposes) Steel Bars
DIN EN 10273 (Hot rolled weldable steel bars for pressure purposes)
Note: There is also a modern DIN EN 17243:2020 standard, but it is unrelated to heat-resisting steels; it covers Cathodic protection of internal surfaces of metallic tanks. Where to Find the PDF
Since the standard is withdrawn, digital copies are typically available through historical archives or standards organizations:
Official Purchase: You can buy archived versions or their EN replacements from DIN Media .
Archival Previews: Some technical documentation and previews can be found on sites like Scribd or GlobalSpec . DIN 17243 - 1987-01
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.
