Austenitic steels are referred as non-heattreable in conventional sense i.e. they can’t be hardened by transformation hardening mechanism (quench & temper)
The only suitable method to increase strength/ hardness of austenitic grades is cold working.
In limited uses a surface treatment such as nitriding can also be tried but at the loss of corrosion resistance, however.
Following heat treatments apply to Austenitic grades:
Solution heat treatment
Stress relieving
