Charpy Test of Inconnel (ASME B 31.3)

[Ilkin Hasanov]

Hi All,

Could you please advise, when does ASME B31.3 require to perform Charpy Test for Inconel Material (UNS 06625)? 

After which MDT it is mandatory to perform it? 

Regard, 

Ilkin HASANOV.

Dear Ilkin,

 

The alloy 625 (Ni-Cr-Mo-Nb) for high temperature service 0-800 C and highly corrosive environment, rarely requires impact testing. ASTM B564 (UNS NO6625) does not state it as proof of its mechanical properties. If this is your case, at what temperature would you perform the Charpy test?

Better: in what temperature range is the service of this alloy located, in your case?

 

Regards,

Ramon Briceno.
