Material Overview – What Is DIN 17740 Nickel 200/201?
DIN 17740 is the German standard covering seamless nickel tubes. Nickel 200 (2.4066) and Nickel 201 (2.4068) are commercially pure wrought nickel materials with excellent corrosion resistance and good mechanical properties.
Nickel 200 contains higher carbon content, while Nickel 201 is the low-carbon version designed for elevated temperature applications to prevent graphite precipitation.
Key Characteristics:
• Nickel content ≥ 99.0%
• Excellent resistance to alkalis
• Outstanding corrosion resistance in neutral and moderately reducing environments
• Good thermal and electrical conductivity
• Excellent fabrication and welding performance
Nickel 201 is typically preferred when service temperatures exceed 315°C (600°F).
