A commercially pure Nickel (typically
99.6% Ni), 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 315o C (600o F). Lower
carbon content also reduces hardness.
Applications include: food and synthetic fibre processing, heat
exchangers, chemical and electrical industries.

strength and elongation drop significantly at temperatures above
315o C (600o F).
Service temperature is dependant on environment, load and size
range.
