SA 516 HARDNESS VALUE BASIS

[212197]

ASME SEC IIA does not specify hardness value of SA 516.
Mill Test certificates indicates maximum permissible hardness value of SA 516.
From where the MILL get that value?

 

[DVWE]

My guess would be a NACE standard.

The devil is in the details; she also wears prada.

 

[david339933]

I would guess NACE as well....was the limit 22HRC or equivalent (235HB)?

 

[EdStainless]

Or have they worked back from max strength/min elong that is allowed?
OF the NACE limit.
Or some limit imposed by a major customer of theirs, so they make it all this way.
Did you ask them?
