What is the effect of the plate material on the measurement?

Hello all,
What is the effect of replacing an orifice plate with another plate of different material? The vendor said that the material A216 is not avialable and instead he will use stainless steel material.
Thanks in advance.

so the calculations for the gas orifice plate will not change, I have only to check the plate deflection as the gas is dry, sweet clean gas.

If the plate is made to the ISO/AGA/API standards then as long as you don't exceed the max allowable dP you don't need to worry about deflection.

"Belief" is the acceptance of an hypotheses in the absence of data.
"Prejudice" is having an opinion not supported by the preponderance of the data.
"Knowledge" is only found through the accumulation and analysis of data.

Anyway, I took for granted that manufacturer has to take care of the flow calculations too (my company operates in this way), so change in material for the end user is only a matter of erosion, corrosion etc.
Regarding deflection, I agree with Dave.
Have a nice day.
