Hardening off is important because it helps acclimate seedlings or young plants to outdoor conditions, reducing transplant shock. This gradual exposure to sunlight, wind, and fluctuating temperatures strengthens the plants' tissues and enhances their resilience. Without proper hardening off, plants may experience stress, stunted growth, or even death when moved to their final outdoor environment. It ensures a smoother transition and promotes healthier, more robust plants.

Hardening of the arteries is bad as it decreases blood flow and limits the amount of oxygen in the body. It can lead to heart attacks and strokes when pieces of plaque break off and block the passages.
mostly is the hardening done by induction hardening machine, I know also manufactures that do this using the flame hardening method.
in my opinion surface hardening is applied only on the surface while the true hardening is applied in the whole part of the metal....
what the was on tooth hardening day?
Arteriosclerosis is hardening of the arteries.
By gradually exposing it to colder temperatures until it is able to stay outside in any weather.
Case hardening, also referred to as surface hardening is the process of hardening a surface of a metal. It is done by surfacing the metal surface with a layer of metal on top of it, in order to harden it.
Sclero means a hardening from the greek word "skleros". Sclerosis means a hardening of the skin.
Case hardening or surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material's surface, forming a thin layer of a harder alloy.
Glomerulosclerosis means hardening of the glomerulus.
