Defines the standard's applicability to rolled strips of specific nickel-iron alloys (e.g., NiFe 45, NiFe 50, NiFe 52) with thicknesses typically between 0.1 mm and 3.0 mm, and widths from 5 mm to 200 mm.
Protection against aggressive chemical media and oxidation .
The latest revised version is DIN 17742:2020-12 . It consists of 9 critical pages of tables, limit thresholds, and guidance notes.
The standard details the specific permissible elemental percentages for high-performance nickel-chromium alloys. It dictates the minimum and maximum boundaries for nickel, chromium, iron, carbon, silicon, manganese, and stabilizing elements like titanium or aluminum.

: Many of these alloys, such as Nimonic 80A, are age-hardenable. They maintain significant tensile and creep-rupture strength at elevated temperatures where standard steels would fail. Environmental Stability
is a German industry standard titled "Wrought nickel-iron alloys with special magnetic properties or specific coefficients of thermal expansion – Chemical composition, properties, and tolerances." (Original German title: Nickel-Eisen-Legierungen mit besonderten magnetischen Eigenschaften oder bestimmten Wärmeausdehnungskoeffizienten ).

The standard covers several specific material numbers (W-Nr.) and alloy designations that are widely used in industrial applications: DIN 17742 - Accuris Standards Store
– Sells DIN standards internationally (US customers).
DIN 17742 specifically covers wrought alloys where nickel is the base and chromium is a primary alloying element. These materials are prized for their ability to withstand extreme temperatures and corrosive environments. ANSI Webstore Key Alloys : Common grades listed under this standard include (NiCr15Fe), (NiCr23Fe), and Nimonic 80A (NiCr20TiAl). Chemical Balance It consists of 9 critical pages of tables,
