[MW:24106] Ferrite No. in Austenistic stainless steel weld overlay in FCAW process

Hello,

I find it bit strange to receive Ferrite no. above 8 or up  to 11 some times, while using FCAW weld overlay on CS surface. What are the reasons behind these. 

My requirement is 3 to 8 % only. 

Can  I have any solution for this ? .

 PWHT  will be there in my job. 

What should I do to restrict up to 8 % only, with same process.  

Warm Regards

Purvin Bhatt
