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

Yes, it is for Grey cast iron.

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

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

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

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

Nice explanation.

18% chromium and 8% nickel.

18/8 steel is called Austenitic.

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.
