If I use LM2596Adj for 12V/3A output. What will be maximum junction/case temperature of LM2596Adj.

What is safe operating temperature so that LM2596Adj will not get damaged.

does temperature stabilizes after some time.

    The operating junction temperature of any regulator depends on the power dissipation, the package thermal constants, the size of heat sink and/or PCB,

    and the ambient thermal conditions.  The data sheet for the LM2596 describes in detail the temperature rise for a given set of conditions. 

    Also, app note SNVA419 gives some helpful suggestions about thermal design.

    The simplest way to design you application is to use the Webench Design tool; it will give you an idea about the junction temperature for a given condition.snva419c-1.pdf

    I have attached the app note.
