[MW:2344] Effect of %Fe in NiCu7 weld overlay

 

 

Dear Sir,

I have a query i.e.

For Monel 400  clad restoration by weld overlay of Nicu7 on SA 516 Gr 70 base , Now a days Process licenser  allows  of Max 2.5% Fe  (earlier they were allowing up to 5% Fe) The equipment is used in refinery  for  HCL fluid service.

 

i)What must be the reason for making stringent requirement

ii) What is the effect of Fe in monel weld for chloride service

I will be thankful to you for guidance in this regard

 

Regards
