the hardness vlaue of carbon very much depends on the value of the hardness of the carbon. if it is a high value then the hardness is high however if it is a low value then it is a low hardness helpful??? :D
In brinell scale ,the hardness value is 180
Yes, a material with a hardness of 8 can scratch a material with a hardness of 7, but not the other way around. Hardness is a measure of a material's resistance to scratching, so a material with a higher hardness value can scratch a material with a lower hardness value.
Q = 1 / Maximum value of Z permissible R = 1/ Maximum value of u permissible

The minimum hardness value for IS 1570 Gr 20C8 material is typically around 197 HB.
twice of the value of circular tolerance
Bromine's hardness is not typically measured, as it is a liquid at room temperature and does not possess a defined hardness value like solid materials.
It is a gas so it doesn't have a hardness unless in solid state
The hardness of a mineral is determined by scratching it with materials of known hardness, such as a fingernail, a copper penny, a steel nail, or a piece of glass. The mineral is assigned a hardness value based on which material can scratch it. This is known as the Mohs scale of hardness.
It is an identity.
