Nickel® 201

Available in any of the 'profile options'

A commercially pure Nickel (typically 99.6% Nickel), Nickel 201 is essentially the same as Nickel 200, but with a lower Carbon content to prevent embrittlement by inter granular carbon at temperatures over 315^oC (600^oF). Lower carbon content also reduces hardness.

Nickel® 201 is also known as Phyweld 201.
