Realistically, if my oven could get as low as 130, could I toss a steak in there and eat it some time later?
An already cooked steak?
You could keep it mildly warm for a while...
An uncooked streak? No.
40-50 Celsius is close to the ideal temperature for bacteria growth, and certainly inadequate for cooking.
Oh I apologize, I didn't realize you were in transition.
