Can a 0.5Mpa saturated steam flange be replaced with a PN16 plate butt weld flange?

Sure, 5 to 16 is no problem.

It works fine; it’s very effective. It’s best if it’s made of forged steel as well

Depending on your operating conditions, if they involve severe cycling, plate flat welding flanges cannot be used; instead, necked butt welding flanges should be employed. Flat-welded flanges should generally be used in combination with soft gaskets and low-strength hex head bolts, for compressed air and industrial water applications where PN≤2.0 MPa and the design temperature is below 150°C
