Emphasis on yield strength at temperature and properties. Common Grades and Properties
The high chromium content allows the formation of a protective chromium oxide layer, while nickel enhances structural stability. 3. Mechanical Properties of DIN 17243 Forgings
By understanding these two distinct standards, you can confidently select the correct documentation and avoid costly specification errors in your engineering projects.
Boiler parts, steam piping, and pressure vessels. 3. 13CrMo44 (Material Number: 1.7335) Type: Chromium-Molybdenum alloyed steel. din 17243 pdf
is a withdrawn German standard that specifies the technical delivery conditions for weldable heat-resisting steel forgings and rolled or forged steel bars .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
One of the most frequently cited grades under this standard is (Material No. 1.0460 ), widely used for manufacturing high-quality flanges. Tensile Strength : Minimum 485 MPa. Yield Strength : Minimum 250 MPa at room temperature.
Standards are not mystical; they are methodical. DIN 17243’s strength comes from structure: Emphasis on yield strength at temperature and properties
Ability to withstand stress at operating temperatures often exceeding 500∘C500 raised to the composed with power C 932∘F932 raised to the composed with power F
Each steel grade had defined maximum and minimum percentages for elements such as carbon (C), manganese (Mn), silicon (Si), phosphorus (P), and sulfur (S).
The standard outlines how the pipes must be treated before delivery (e.g., normalized, annealed, or tempered). This ensures that the metallurgical structure of the steel is stable and ready for welding and installation. Mechanical Properties of DIN 17243 Forgings By understanding
The standard specified minimum values for yield strength (Rp0.2), tensile strength (Rm), elongation (A), and reduction in cross-sectional area (Z) depending on the material’s heat treatment condition.
Manufacturers outside of Europe (e.g., in Asia or the Americas) frequently encounter vintage blueprints requesting DIN 17243 compliance.
At room temperature and elevated operational temperatures.
Minimum requirements for yield strength at room temperature, elevated temperature yield strength ( Rp0.2cap R sub p 0.2 end-sub ), tensile strength, and elongation.
