Yes, if this is your typical capacitor peak charge circuit, then the diode bridge is the only part at risk. You must keep the surge current less that the diode rating. If the diode has a 350A surge rating then you need a current limiting resistor greater than:
R = 170V/350A = 0.5 ohm

Please remind me, on a cold start, with the capacitors unloaded, is the diode bridge at risk at all?
