When ordering semi-finished products, your purchase order must reference the correct standard. Copying the precise designation (e.g., Werkstoff 2.4473 according to DIN 17742) from a PDF avoids costly mistakes.
A "DIN 17742 PDF" will typically list material designations that correspond to international grades. Here are the most common ones you will encounter: din 17742 pdf
| DIN 17742 Designation | Common Trade Name | Key Characteristic | Typical Application | |----------------------|--------------------|--------------------|----------------------| | 2.4496 | NiFe 48 | High permeability at low induction | Relay cores, transformer laminations | | 2.4499 | NiFe 72 (Mu-metal) | Very high permeability | Magnetic shielding (medical, electronic) | | 2.4541 | NiFe 54 (Radiometal) | High initial permeability | Sensitive magnetic amplifiers | | 2.4473 | NiFe 36 (Invar) | Extremely low thermal expansion | Precision instruments, LNG tank supports | | 2.4475 | NiFe 42 (Kovar-type) | Matches glass/ceramic sealing | Transistor headers, integrated circuit packages | Here are the most common ones you will
Without DIN 17742, manufacturers would have no unified reference for producing these specialized alloys. The PDF version of the standard provides precise tables that chemists and metallurgists rely on daily. DIN EN 10045 for tensile testing
Defines the field of application and lists other standards (e.g., DIN EN 10045 for tensile testing, DIN 50125 for test pieces).
