is a German technical standard that specifies the chemical composition of wrought nickel-chromium (NiCr) alloys. The current version of this standard is DIN 17742:2020-12 , which replaced the 2002 version. Guide to DIN 17742 1. Scope and Application
The standard is the definitive material specification published by the German Institute for Standardization (Deutsches Institut für Normung) governing the chemical composition of wrought nickel alloys with chromium . Updated recently to ensure global cross-compatibility, the standard serves as a bedrock for aerospace, chemical processing, and marine engineering by dictating exact element balances required to survive extreme high-temperature and highly corrosive environments.
Valve seats, spindle nuts, piston rods, and heavy-duty sliding bearings.
DIN 17742 was developed by the Nickel Working Committee (NA 066-03-04 AA) within the DIN Standards Committee Nonferrous Metals (FNNE), the body responsible for standards related to non-ferrous metals in Germany. din 17742 pdf

The primary focus of DIN 17742 is the of wrought nickel-chromium alloys. Unlike standards that may also cover dimensions, tolerances, or mechanical properties in depth, DIN 17742 is specifically dedicated to the elemental makeup of these materials.
Whether you are verifying a material certificate or sourcing a high-performance alloy, here is a breakdown of what DIN 17742 covers and why it matters. What is DIN 17742? DIN 17742 is a technical standard published by the German Institute for Standardization (DIN) . It specifies the required chemical composition
A PDF version of DIN 17742 details the permissible chemical ranges for elements including nickel (Ni), chromium (Cr), titanium (Ti), aluminum (Al), iron (Fe), and molybdenum (Mo). Approximate % Range Role in Alloy Remainder (~60-75%) Base metal for high-temperature strength Chromium (Cr) Oxidation and corrosion resistance Titanium (Ti) Strengthens through precipitation hardening Aluminum (Al) Enhances oxidation resistance Iron (Fe) Cost-effective matrix component Scope and Application The standard is the definitive
The standard outlines several critical parameters to ensure material consistency and reliability:
We recommend that companies involved in the production, processing, and use of nickel and nickel alloys familiarize themselves with DIN 17742. The standard provides valuable information on the chemical composition, mechanical properties, and testing methods of these materials, which can help to ensure that products meet specific quality standards.
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.
Applicable to sheet, strip, plate, tube, bar, wire, and forging stock. 2. Common Alloy Grades
