[MW:27407] Use of Flux wire combination for SAW welding

Hello Experts,


In SAW welding; My WPS (as per ASME SECTION IX) calls for F7A6-EH12K combination but my flux supplier has provided me F7A6-EH10K rated flux. Is this acceptable?
Flux supplier says that as it is already tested with lower manganese level wire hence it qualifies for use with EH12K wire also which possess higher manganese and silicon.

Can someone guide me on this?

Regards,
Ankur Pandey
