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.
The Brinell hardness test is a standardized test in material science. It measures the hardness of a metal by measuring the indentation on the material caused by an indenter.
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.
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.
The Brinell hardness of plutonium is 242, the Vickers hardness is 255.
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.
Technetium is a relatively soft and malleable metal with a hardness comparable to that of silver or lead. It can be easily cut with a knife and has a low melting point, making it relatively easy to work with in a laboratory setting.
Plutonium has a metallic luster, similar to other metals. It is a relatively soft metal with a hardness of about 2.5 on the Mohs scale, making it easy to cut and shape.

Thorium is a relatively soft and malleable metal, similar to lead, that can be easily cut with a knife. It has a Mohs hardness rating of 3, which is softer than many common minerals like quartz and feldspar.
