I just got a brand new pressure reducing valve, but there are a lot of chips(see the photo attached) on the top when I take it out of the box. I am concerned if these chips make the top part get corrosion very easily. What are the top part made of and why the manufacturer paints it? I assume the painting helps to prevent the corrosion. Thanks .

i would not worry , keep your bill most parts companies guarantee parts for a year or more. install it with a pressure gauge so that you can see if it works correctly and hold the pressure at what you want .
Thanks for the response. The reason I ask this question is to make sure the chips don't cause more/easy corrosion as the plumber charge $450 on labor to install the pressure reducing value and I don't want to ask plumber to redo the work in case of the issue from parts.
The top of those PRVs are cast iron. Cast iron rust is inconsequential here because the iron is thick and it never penetrates significantly because it is not in constant water contact. It is made for outdoors.
The rubber diaphragm usually fails due to degradation from our water treatments.
for example, there are cast iron cannons still around under the sea in shipwrecks and bridges built in the 1700's exposed to water all this time.
