Max. Hardness Duplex Nace

[DiplingAndre]

Can anyone tell me what is the max. hardness for duplex ss acc. Nace MR0175 and where i find it? I just found a value of 25 HRC for HIP but I need it for cast steel.

There are no stipulated hardness limits for wrought and cast material.

It would be whatever the material specification requires.
