Hi,
My company sells SS316 valves (bought) which get welded to SS316L weld neck flanges which we manufature ourselves from bar-stock.
A client of ours questions our welding SS316 to SS316L.
This should have a higher risk of corrosion.
They suggest it is necassary to use SS316L/SS316L.
I think we are ok because we never saw any problems with our product, but I don not realy know the actual difference between the SS316L/SS316L weld and the SS316/SS316L weld.
I know SS316L is weld quality and has a carbon content of max. 0.03%. But can someone please help me understand why someone would think that a system containing a SS316/SS316L weld is of less corrosion resistance than a system containing SS316 and SS316L but NO SS316/SS316L welds?
Your help would be greatly appreciated,
