Toughness is the ability of steel to absorb energy.
Hardness is the ability of steels to withstand wear. Hardness is the ability of material to withstand the indent and is measured in rockwel or vickers. also it is a measure of stiffness of material. but hardenability is ability of material to become hardened by various methods of hardening such as carburising or quenching. it is firmly dependent on quantity of carbon in that material. and actually it doesn't have any measuring unit !
impact strength is sudden load bearing capacity & toughness is steady load bearing capacity.
A tensile test is performed by stretching the material until it breaks. An impact test is performed by applying a sudden shock to the material so that it fractures.
Viscostity is the thickness of a fluid and hardness is of a solid. for example, u would b measuring the viscosity level difference between ketchup and water. water is thin and it's flow rate is fast but ketchup has high viscosity so it's flow rate is slow -zainab
Both the properities are having the ability to absorb the energy,but they differ in elastic properity,If the same amount of energy being absorbed by the materials having mechanical properity of toughness and stiffness,The elastic range of tough material is more ,than the stiff material when compared.Spring material is tough,but Low carbon mild steel with annealed heat treatment if stiff,Hence the difference can be made between them,
> Color > Hardness > Melting Point > Flammability to name a few ...
what is the difference between Shore-A Hardness & Barcol Hardness
Hardness or toughness
The difference is dobby the elf who made babies with a trout.
read from engineering material
impact strength is sudden load bearing capacity & toughness is steady load bearing capacity.
The hardness of corundum on mohs scale is nine(9)
The difference between strength and hardness is that the strength refers to the force that is present between the bonds. Strength attributes to how strong or weak the force between the bonds. Hardness refers to the nature of the force, which basically is how rigid or flexible the bonds between particles.
It is a difference between the hardness, generally expressed in the Mohs scale.
micro is on a small scale and macro on a larger scale

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.
