To ensure compliance, it is critical to use the latest, authoritative version of the standard.
DIN, like all major standards bodies, regularly harmonizes national standards with international ones. DIN 17243 was officially (zurückgezogen) in the early 2000s. Standards organizations do not sell or promote withdrawn documents because they are obsolete.
The DIN 17243 standard covers forgings and rolled bars made from elevated-temperature structural steels. These materials are engineered to maintain mechanical strength, oxidation resistance, and structural stability at temperatures up to 600°C (1112°F).
High-temperature components like collectors or container courses.
It is essential to note that (Steel forgings for pressure purposes - Part 2: Ferritic and martensitic steels with specified elevated temperature properties).
| Diameter (mm) | Tensile strength Rm (MPa) | Yield strength Re (MPa) | Elongation A (%) | |---------------|---------------------------|-------------------------|------------------| | ≤ 40 | 610–780 | ≥ 390 | ≥ 14 | | >40–100 | 590–760 | ≥ 370 | ≥ 15 |
Covers forgings, hot pressed parts, and rolled or forged steel bars.
High-pressure steam pipes, valve bodies, and boiler components.
Materials sourced under this specification are typically utilized in heavy industries where high pressure and thermal cycling occur simultaneously:
At its core, it was designed for components that operate where most materials fail: under the intense thermal stress of steam boiler plants, pipework, and pressure vessels. The Protagonists: The Steel Grades
