Nickel 201 (For Springs)
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°C (600°F). Lower carbon content also reduces hardness.
Nickel® 201 is also known as Phyweld 201.
Nickel Base Wire for wire springs, flat springs and wire products
