ASME has no requirement.
VDM alloy 59 is a Ni-base alloy and normally, there are no hardness requirements for FCC alloys (full austenite or Ni-base) unless they are to be used at low temp service (Cryogenic service).Regards

Dear Ganesh sir,--
Hardness values are dependent upon factors such as alloy content, weld preheat and postweld heat treatment. Specific hardness test for welded joints are not specified in asme sec -ix except Temper bead and overlay .
in your case hardness test is not required for low carbon nickel-chromium-molybdenum-copper alloy steel
but it is also defend upon specification of your customer ,design application or service application so refer your specification of customer
