Wrought nickel alloys with chromium - Chemical composition ( Nickel-Knetlegierungen mit Chrom - Zusammensetzung Current (2020-12 edition)
Alloy 2.4475 must match the expansion of borosilicate glass. The PDF provides the exact curve of expansion from 20°C to 450°C. A mismatch, even by 5%, results in cracked seals and hermetic failure. din 17742 pdf
Mu-metal (2.4499) requires a specific annealing cycle in hydrogen atmosphere. The DIN 17742 PDF includes mandatory notes on heat treatment to achieve the specified permeability (μ4 ≥ 60,000). A non-compliant alloy will allow stray magnetic fields, ruining image quality. Wrought nickel alloys with chromium - Chemical composition
To understand the weight of DIN 17742, one must understand the material science behind the alloys it governs. The Nickel-Iron-Chromium family of alloys is renowned for its exceptional resistance to oxidation, carburization, and high-temperature corrosion. Mu-metal (2
