Hardness of a material depends on the type of bonding between atoms.
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.
what is the normal hardness of en8 material
EN31 is steel that has a hardness measurement of 63HRC. The Brinell-Rockwell hardness of the material ranges from 59 to 65.
IS 2062 standard does not specify any Hardness Limit for the material. As such, even the equivalent SA36 does not specify anything on Hardness. But this being a P No.1 material in properties, the commonly accepted Hardness limit is 200HB or 93 HRB. Again there can be variation based on specific application/project requirements.
approx. 50 HRC after hardening and tempering
It depends on the material in question!
False
A mineral's resistance to being scratched (or when a force is applied) is called its hardness.There are different measurements of hardness: scratch hardness, indentation hardness, and rebound hardness. A material's hardness depends on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity.
Tablet hardness get affected by 3 factors:1) Material related factors: Compressibility of drug, binder type and concentration, Moisture content of blend etc..2) Process related factors: Dwell time, Force, Die fill weight3) Machine related factors: Type of tooling, Vibration of machine4) Environmental factors: Temperature, Humidity
Because the hardness is not dependent to the size of a material sample.
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.
No matter what size a sample is, if is hard, it will still be just as hard. This means that hardness is an intensive properties. Intensive properties do not matter what size of sample is being used. Extensive properties will change if sample size is changed.
hardness is that property of material by virtue of which, the material cfan resist abrasion, wear and tear, penetration etc.
Hardness: the measure of the resistance of a solid to being scratched or dented ?
the hardnessb of a material

Yes, hardness is a specific property of each material.
