Varies depending on the electroylite solution used (several). Can be hard to soft. Electroless Nickel is typically a more advanced form of (industrial) plating and the low phosphorus variety can achieve hardness's up to Rockwell "C" rated or HRC 60 which is very hard, like hardened steel.
So, is it an industrial coating (electroless) or is it being plated over steel to receive a chrome finish (automobile bumper)?
Typically the introduction of impurities into nickel actually makes it harder as pure nickel is quite soft and malleable.
Hope this helps.
Minimum hardness of Mild steel is about 140 Vickers hardness.
In Vickers hardness test the for used is much lighter than the force used in Rockwell hardness test, The Rockwell hardness test is the considered to be the most routinely used technique to measure the hardness of materials because of its simplicity and because it does not require specific skills in order to perform it.
I need to know the hardness for c - 45 steel.
The Rockwell C Hardness system uses "HRC" as a measure of hardness for various materials. A hardness of 68 HRC is extremely high and will most likely be harder than simple steel.
EN31 is steel that has a hardness measurement of 63HRC. The Brinell-Rockwell hardness of the material ranges from 59 to 65.
The formula to convert Vickers to Brinell hardness is: Brinell Hardness = (2.025 x Vickers Hardness).
It is estimated that the Vickers hardness of promethium is 617,8 MPa.
Minimum hardness of Mild steel is about 140 Vickers hardness.
HV = 2.9 * Y Where HV - Vickers hardness Y - Yiekd stress in KG/mm2
The Brinell hardness of technetium is 112.The Vickers hardness of technetium is 151.
Nickel has a hardness of 4 on the Mohs scale.

I don't found the Mohs hardness of plutonium but: - the Brinell hardness is 242 at r.m. - the Vickers hardness is 255 at r.m. After a hardness conversion chart an equivalent Mohs hardness may be 3,7.

ElectroPlated Nickel Silver
The acronym EPNS stands for electroplated nickel silver. This is commonly seen on silver flatware and serving pieces. It is the most common of all the stamps seen on these items.
