we are going to welding a manhole nozzle with welding neck flange. the nozzle material is A240 type 321. which flange material is suitable for this- A182 F1 or F321?

It is recommended that both welding components have similar chemical composition because different composition may lead to galvanic corrosion,
A182 F 321 is a good choice.
