Gents,

I have a query on typical carbon steel swivel flange suitability with Incoloy 825 gasket and carbon steel weldneck flange with Inconel 625 overlay on the groove.

Is it possible to fit both flanges, one with Inconel 625 overlay against non-overlay groove? Carbon steel would be able to compress the gasket, surely. But I'd like to know on material compatibility between the non-overlay groove and Incoloy 825 gasket.

Appreciate your help, thank you.
