Nickel 201 Sheets

Nickel 201 Sheets
Introduction
Nickel 201 is a commercially pure wrought nickel alloy similar to Nickel 200 but with much lower
carbon content. This lower carbon level prevents graphite formation at elevated temperatures,
making Nickel 201 suitable for high-temperature applications. Nickel 201 sheets are widely used in
chemical processing, electronics, and thermal applications where purity, corrosion resistance, and
temperature stability are required.
Material Overview
Nickel 201 sheets provide:
• Excellent resistance to corrosion in reducing environments
• Superior performance at elevated temperatures compared to Nickel 200
• High thermal and electrical conductivity
• Good ductility and formability
• Resistance to stress corrosion cracking
Because of its low carbon content, Nickel 201 is preferred for service above 315°C.
