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.

Explian about cryogenic hardening?
Cryogenic hardening is often referred to cryogenic treatment and cryogenic processing. Using the term "hardening" is not correct. Cryogenic treatment does not increase the hardness of metals (I.E. rockwell hardness). Rather it changes metals on the molecular level so that they perform better. Cryogenic treatment is used for a variety of reasons including improving dimensional stability, stress relieving, increasing wear resistance, and eliminating walk and creep. A typical cryogenic treatment lasts for several days. Metal and steel parts will be put in a cryogenic processor at room temperature. The temperature will slowly be taken down to -300F below. Then it will hold there for 12 to 24 hours depending on the company doing the treatment. After that, the processor will have the temperature raised back to room temperature very slowly. Finally, the parts will be post-tempered to finalize the cryogenic treatment. Cryogenic treatment re-aligns the micro-structure of the metal to improve its structural stability. Retained austenite will be converted to martensite which allows for a tougher piece of metal. The eta-carbides in the metal will become precipitated which allows for a much higher degree of wear resistance. Below are some good sites for additional reference...
What is the difference between steel and stainless steel?
While stainless steel is an alloy of steel, the primary difference between stainless steel and other steels is that the stainless steels have a high percentage (about 10% or even more) of the element chromium in them.
What is the difference between tin plate and stainless steel?
a tin plate is tin and a plate, and stainless steel is stainless steel.
Difference between duplex stainless steel and stainless steel?
There's no difference, cause duplex is a type of Stainless Steel, as so ferritic,austenitic,martensitic.
What is the difference between stainless steel and real stainless steel in refrigerators?
Well, the answer lies in the question; by saying 'real' stainless steel, you are implying that there are fake metals which go under the name 'stainless steel', thus the difference is that the stainless steel in refigerators is actually stainless steel, and the fake stainless steel is not...thus your question is answered...

What is the difference between stainless steel and normal steel?
stainless steel has chromium added to the steel, which forms a protective oxide layer at the surface, preventing corrosion (rust).
