This specification covers the requirements for electroless nickel deposited on various materials. This deposit has been used typically to provide a uniform build-up on intricate shapes, to improve wear and/or corrosion resistance, or to improve solderability on or for selected materials, but usage is not limited to such applications. The deposit has been used in service up to 1000 Â°F (540 Â°C) although wear and/or corrosion resistance may degrade as service temperature increases.
