This standard ensures that nickel alloys used in sensitive applications (like chemical processing, aerospace, or industrial heating) maintain structural integrity under extreme stress and heat. The standard is often used for materials such as (Werkstoff Nr. 2.4952), a popular superalloy used for its high creep strength. Key Materials Covered
The currently active version is (published May 2021). Always check for updates, as older copies (e.g., 2010 or 2002) may be withdrawn.
The primary scope of DIN 17742 is to catalog the chemical limits and foundational characteristics of semifinished wrought nickel alloy products where chromium serves as the main alloying element. din 17742 pdf
Standardization organizations like DIN ensure uniformity on a global scale. When suppliers adhere to DIN 17742, it guarantees that a specific alloy designation will perform identically, regardless of the foundry or manufacturer. This predictability is critical when designing parts that will be subjected to extreme thermal cycling or corrosive media.
The standard is titled "Wrought nickel alloys with chromium - Chemical composition" ( Nickel-Knetlegierungen mit Chrom - Zusammensetzung ). The standard strictly defines the chemical composition and limits for semi-finished wrought nickel alloy products where chromium serves as the primary alloying element. Document Profile This standard ensures that nickel alloys used in
When ordering semi-finished products, your purchase order must reference the correct standard. Copying the precise designation (e.g., Werkstoff 2.4473 according to DIN 17742 ) from a PDF avoids costly mistakes.
The keyword is commonly searched for three main reasons: Key Materials Covered The currently active version is
: Applied in specialized components like cathode-ray tube spiders and high-temperature springs. VDM-Metals 4. Fabrication Standards
This standard specifically covers soft magnetic alloys (such as Permalloy, Mu-metal, and Radiometal) and controlled-expansion alloys (such as Invar and Kovar-type materials). It defines:
Excellent resistance to chloride-ion stress-corrosion cracking and high-purity water.
