This includes thickness tolerances for cold-rolled strip (e.g., ±0.01 mm for thickness under 0.5 mm), width tolerances, edge camber, and flatness.
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

: A low-carbon version (Alloy 600 LC) for improved resistance to intergranular corrosion. A mismatch, even by 5%, results in cracked
In the world of precision engineering and temperature control, standards are everything. One of the most critical documents for manufacturers, quality engineers, and R&D departments working with thermostatic bimetals is . This German industrial standard governs the technical delivery conditions for rolled strips made of nickel-iron alloys specifically designed for thermostat bimetals.
A critical aspect of analyzing DIN 17742 is recognizing its position within the broader evolution of European standardization. For decades, national standards like DIN were the primary reference for industry in Germany and much of Europe. However, with the formation of the European Union and the drive for a unified market, there has been a concerted effort to replace national standards with European Norms (EN).
When you receive a mill certificate from a supplier claiming compliance with DIN 17742, cross-check it against the PDF’s requirements. Look for:
