Heat treating of high carbon steel to harden it is an instantaneous process. The steel is heated red hot, causing the formation of crystals of very hard type of Iron Carbide called "Martinsite". If cooled slowly, the Martensite reverts to iron and carbon again and the steel remains soft. But if cooled rapidly by plunging the red hot steel in water or oil, there is insufficient time for the Martinsite to break down to iron and carbon, and it remains as crystals of very hard Martinsite, imparting hardness to the steel.

Difference between air hardening and stainless steel?

There isn't really a difference since a piece of steel can both stainless and air hardened. Stainless steel is a steel alloy with a minimum of 10% chromium content by mass. Metals can be hardened in a variety of ways. They may be work hardened, tempered, air or oil hardened, for example. Tempering, or the systematic heating, cooling and reheating of a material is one technique that might be used to harden steel.

Why does hardened steel rust faster?

Hardened steel can rust faster than regular steel because the hardening process can disrupt the steel's natural corrosion resistance. This can lead to increased vulnerability to rust and other forms of deterioration. Hardened steel may also have more exposed surface area due to the hardening process, which can make it more prone to rusting.
