What is hardness of en8 in joules?

The hardness of a material like EN8 is typically measured using a Rockwell hardness scale (e.g., HRC or HRB), which is not measured in joules. Hardness is a measure of a material's resistance to deformation, while joules are a unit of energy. The hardness of EN8 would depend on the specific heat treatment and method of testing used.

What is correlation between tablet hardness unit N and Kp?

Tablet hardness is a measure of the force required to break a tablet, typically in units of N (Newton). Kp (kiloponds) is a unit of force as well. There is a direct correlation between tablet hardness in N and Kp, as they both measure force, with 1 Kp equaling 9.80665 N.


Does density of Thorium mean the same as the hardness?

No, density and hardness are not the same property. Density is the mass per unit volume of a substance, while hardness refers to a material's ability to resist deformation or scratching. Thorium has a high density but its hardness can vary depending on its alloy composition.
