DIN 17243 is a foundational standard for selecting high-temperature materials for forgings. By understanding the specifications outlined in this standard, engineers can ensure reliability in critical high-temperature, high-stress applications.
This standard covers forged or rolled products (like bars and rings) that must maintain strength and creep resistance at elevated temperatures.
is a withdrawn German standard that specified technical delivery conditions for freely machinable steels — specifically, automaton steels (e.g., 9SMn28, 9SMnPb28). These are steels with added sulfur or lead to improve machinability for high-speed automatic lathes.
The closest US grade is AISI 6150 (SAE J404). However, SAE 6150 has slightly different vanadium and carbon content. Always check cross-reference tables. din 17243 pdf
Common grades often associated with this type of technical standard include martensitic steels like
Resistance to scaling and corrosion in gaseous atmospheres at high temperatures.
Typical Chemical Composition Blueprint (e.g., Grade C22.8 / 1.0460) : 0.18 – 0.23% Silicon (Si) : 0.15 – 0.40% Manganese (Mn) : 0.40 – 0.90% Phosphorus (P) : ≤is less than or equal to Sulfur (S) : ≤is less than or equal to Chromium (Cr) : ≤is less than or equal to DIN 17243 is a foundational standard for selecting

The standard enforces strict limits on carbon (C), silicon (Si), manganese (Mn), phosphorus (P), and sulfur (S), alongside alloying elements like Chromium (Cr) and Molybdenum (Mo). Low sulfur and phosphorus limits ensure the steel remains clean and resistant to brittle fracturing. Mechanical Properties Materials must pass rigorous testing protocols, including:
DIN 17243 is officially and replaced by the European standard EN 10222-2 ( Steel forgings for pressure purposes – Part 2: Ferritic and martensitic steels with specified elevated temperature properties ).
