While the modern engineer may turn to EN standards for new builds, the remains a vital artifact of engineering history. It represents decades of German engineering precision in the field of high-temperature alloys. Whether you are maintaining a vintage refinery or researching the properties of Cr-Mo steels, understanding the contents of this standard is essential for safety and compliance.
To ensure compliance, it is critical to use the latest, authoritative version of the standard.
is a withdrawn German standard that specifies the technical delivery conditions for weldable heat-resisting steel forgings and rolled or forged steel bars .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

High-temperature components like collectors or container courses.
DIN 17243 specifies the technical delivery conditions for semi-finished products, hot-formed bars, and forgings made from heat-resisting steels. These materials are primarily used in the construction of pressure vessels, boilers, pipelines, and valves that operate continuously at elevated temperatures (typically above 400°C). Current Status: Superseded by EN 10222-2
is a withdrawn German technical standard that specified the delivery conditions for weldable heat-resisting steel forgings . It was primarily used in the manufacturing of pressure vessels, boilers, and piping systems designed for high-temperature service. Status and Replacement Current Status: Withdrawn. While the modern engineer may turn to EN
In the world of technical standards, clarity is paramount. However, confusion can arise when a single standard number refers to two entirely different topics. This is precisely the case with DIN 17243, a designation that currently points to two distinct German industrial standards (see below). This comprehensive guide will clarify the history and scope of both, providing a definitive resource for engineers, procurement specialists, and quality assurance professionals.
A chromium-molybdenum steel designed for high stress and temperatures up to 560°C.
The confusion around "DIN 17243" stems from the replacement of an older material specification with a newer, unrelated corrosion protection standard in the 2000s. Both standards are currently available from standards distributors, but they serve vastly different industries. To ensure compliance, it is critical to use
