Ya. you can use 17 instead of 16. because it will give extra strength to any joint.

Dear friends
We have a WPS for welding 321-SS base metal with ER 308h+E 308h-16 which is approved by PQR but the matter is non-availability of E308H-16 and we would like to use E308H-17 instead.
There is no mechanical and chemical difference between these two according to ASME Sec II Part C, the only difference is in cover composition that makes -17 better for fillet welds in comparison with -16. But the question remains because our joint is groove and not fillet. What's your opinion? Could -17 be used for groove welding instead of -16 ( without need of a new WPS and PQR) ?
