[MW:9004] Re: ER Ni Cr Mo-3 WELD OVERLAY

Dear Rinshu,

Please note that in the Inconel Weldoverlay(ER Ni Cr Mo-3). There is
restriction of Fe not Ferrite.

Most of the time Fe is restricted to maximum 5%.

You are getting Fe 0% is good because most of the time welding
engineer is struggling to maintain Fe below 5%

Best Regards,
