standard is a critical technical specification that defines the chemical composition and requirements for wrought nickel-chromium (Ni-Cr) alloys

. This standard is essential for ensuring material consistency across high-performance industries like aerospace, chemical processing, and power generation. 1. Scope and Composition

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

: The standard dictates precise ranges for chromium—often between 15% and 30%—and minor but vital additions like aluminum, titanium, and carbon. VDM-Metals 2. High-Temperature and Corrosion Properties

Materials compliant with DIN 17742 are engineered for "extreme service." Oxidation Resistance

: The high chromium content allows these alloys to form a stable, protective oxide scale that resists scaling at temperatures up to Mechanical Strength

: 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

: They exhibit excellent resistance to chloride-ion stress-corrosion cracking and various acidic environments, making them "standard" for nuclear reactors and chemical "bubble towers". 3. Industrial Applications

Because DIN 17742 ensures specific material properties, these alloys are found in critical components:

: Used for turbine blades, engine exhaust liners, and seals that must handle high thermal stress. Power & Chemical

: Found in furnace muffles, radiant tubes, and heat-treating baskets. Electronics

: Applied in specialized components like cathode-ray tube spiders and high-temperature springs. VDM-Metals 4. Fabrication Standards din 17742 pdf

The standard often works in tandem with other DIN specifications for different product forms. For instance,

might be used for rods and bars, while DIN 17742 defines the base chemistry. Compliance ensures that the alloy can be successfully welded (using matching fillers like VDM FM 699 XA) and machined using specific cooling strategies to handle its tendency to work-harden. VDM-Metals

In summary, DIN 17742 provides the metallurgical blueprint for the nickel-chromium superalloys that power modern heavy industry. You can find detailed technical datasheets for these materials on professional portals like VDM Metals Special Metals comparison table

DIN 17742 defines technical requirements for wrought nickel-chromium alloys, focusing on chemical composition, mechanical properties, and material forms, with a key alloy being NiCr20Ti (2.4951/Nimonic 75). These alloys are critical for high-temperature applications in aerospace, gas turbines, and industrial furnaces due to their oxidation resistance. Official, authorized copies of the standard are available through distributors such as Beuth Verlag or DIN Media.

DIN 17742 is a German technical standard that specifies the chemical composition of wrought nickel alloys with chromium. Released by the Deutsches Institut für Normung (DIN), the latest active version is DIN 17742:2020-12 . It replaces the previous 2002 edition . Scope and Applications

The standard defines the required chemical makeup for semi-finished products—such as sheets, strips, and rods—made from wrought nickel alloys where chromium is a primary alloying element . These alloys are selected for environments requiring:

High-Temperature Strength: Maintaining structural integrity under extreme heat .

Corrosion Resistance: Protection against aggressive chemical media and oxidation .

Specialized Physical Properties: Controlled thermal expansion, electrical resistance, or specific magnetic characteristics . Common Alloy Grades

Materials defined under DIN 17742 often correspond to well-known UNS (Unified Numbering System) grades. Key examples include:
