Heat Resistance of Electroless Nickel Plating, Nickel ...

A. Above 220 °C electroless nickel + 10% Phos begins to form Ni phosphides, recrystallize, harden and shrink. Its corrosion resistance is reduced. At temperatures above 400 °C it begins to lose hardness and corrosion resistance is reduced even more. Above 550 ° C its hardness will fall to around 200 HV. Beyond that you are getting close to its melting point of only 890 ° C (very low for ...
