If you acquire a copy of the document, here is how to efficiently utilize the feature set of the PDF:
Forgings must undergo precise heat treatment cycles, such as normalizing (N) or quenching and tempering (QT), to achieve the required microstructure. Current Status: DIN 17243 vs. EN 10222-2
: Power plant systems handling superheated steam. Pressure Vessels : Chemical and petrochemical reactors. 2. Core Steel Grades Covered in the Standard din 17243 pdf
If you are working on a modern project, you likely need the current EN equivalents rather than the retired DIN 17243. For steel forgings for pressure purposes.
In the process of European harmonization, DIN 17243 was replaced by DIN EN 10216-2 . If you acquire a copy of the document,
The principal edition of this standard is . It provides precise metallurgical guidelines to ensure components can withstand high operational pressures and elevated temperatures without losing structural integrity.
Various commercial websites offer detailed technical information derived from DIN 17243 — including chemical compositions and mechanical properties for grades like P250GH, 20Mn5, and C22.8 — without providing the full standard PDF. Pressure Vessels : Chemical and petrochemical reactors
The standard applies to non-alloy and alloy steel forgings, open-die forgings, and drop forgings. It also covers hot-rolled or forged steel bars used predominantly for manufacturing pressure-containing parts where both are required. Key Applications
