Din 17742 Pdf [upd] Jun 2026

DIN 17742 is a German industrial standard titled "Wrought nickel alloys with chromium - Chemical composition" (in German: Nickel-Knetlegierungen mit Chrom - Zusammensetzung ). Published by the Deutsches Institut für Normung (DIN), this standard exclusively specifies the chemical composition of semi-finished wrought nickel alloy products where chromium is the primary alloying element. It provides the material codes, technical delivery conditions, and guidelines for the preferred applications of these critical materials.

Engineering professionals and procurement teams frequently need to reference the official to verify alloy limits, yield strengths, and tensile requirements for project compliance.

Specific requirements for tensile strength, yield point ( Rp0.2cap R sub p 0.2 end-sub Rp1.0cap R sub p 1.0 end-sub ), elongation at break, and hardness values. DIN 17742 is a German industrial standard titled

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.

The standard applies to various forms of semi-finished products, including: Approximate % Range Role in Alloy Remainder (~60-75%)

An engineer needs a material with a CTE (coefficient of thermal expansion) below 1.5 × 10⁻⁶ /K from -40°C to +85°C. DIN 17742 PDF confirms that NiFe 36 (2.4473) meets this. Without the standard, they might mistakenly use generic Invar, which could have higher carbon content and fail at temperature extremes.
