if a pipe and flange is of carbon steel, then orifice plate (to be installed in that pipe/flange) will be of carbon steel or any other material (Stainless steel etc) can be used ??

RE: Material
If you are referring to galvanic corrosion between CS and SS, there is a very low corrosion potential between the two materials..... Virtually no corrosion between the two.
Additionally, the orifice gaskets tend to electrically isolate the two materials.

The other way around, i.e. small C stl element in a Stl Stl one where galvanic corrosion can occur can eat C Stl very quickly.

RE: Material
You need something that will nearly zero corrosion and erosion in your media, at velocities much higher than the pipe sees.

RE: Material
Galvanic corrosion between the CS piping and SS orifice plate is negligible. However, carbon pick-up by the SS plate could be an issue. Always better to use a low carbon SS.
RE: Material
Following careful shearing, squares of sheets are machined/laser cut to circular discs. Other methods such as stamping or burning the plate blanks are relatively inaccurate. Plates are typically finished to 15-30 micro-inch roughness, applied by special sanding machines designed to preserve the flatness of each plate. Fabrication methods avoid procedures which may damage the bore accuracy or the plate finish.
