Austenite stainless steel shouldn't be heat treated. So the only way is by cold working.

When the material will hardening then atoms will synching and cold working is can capture that strength at any temperature.

Purpose of hardening is to cool the metal from austenite region to room temperature by adopting the cooling rate greater than critical cooling rate, by this process austenite steel will be converted to martensite which is the hardest phase.

18/8 steel is called Austenitic.

18% chromium and 8% nickel.

Nice explanation.

Austenite stainless steel has austenitic structure at room temperature due to the presence of austenitic stabilizers.
So it is only hardened by cold working.
So it is only hardened by cold working.

Austenite structure when cooling from critical point then martensite will formed which is hard.

Normalising is used in austinitic steel to increase hardness and strength. It's there in ace material. Is this correct?

Don't follow ace. It will tell you for Grey cast iron C% 0.75.
