[MW:12684] PQR of overlay



--
Dear,

We would like to qualify the overlay procedure of 316L on SA 516 matl. We are using  309 MoL for  barrier layer and then 316L. But problem is that We have filler wire of 309MoL which have Cr-21.7% (req.is 22-25%) rest chemistry is ok as per section IX. So, will it make any problem in overlays chemistry? and what happen if Cr % is less. 




Regards,
Vishal
