[MW:10269] Effect of ferrite element on 347H material

Dear Goswami,
                         Can you please explain to us the purpose of checking ferrite element in 347H SS matl.
 
What is the requirement of ferrite in 347 material  ?
What are effects of ferrite if found high or low in 347 SS matl ? 
How it can be lowered or maintained correctly in the welding process or material. ?
 
Thanks & Regards,
 
Shaji Nair
