Re: [MW:18817] Clad plate heat treatment as per SA 264 after explosion bonding

The issue is the following:

The explosion bonding process will affect the properties of the 304 austenitic s.s?

With other worlds: the explosion bonding will lead to a precipitation of the chromium carbides and therefore a solution annealing heat treatment will be necessary to get a solution of those carbides in the 304 matrix?

Can your material manufacturer guarantee the properties of 304 without heat treatment?

Could you ask for the parameters of the explosion bonding process?
Could your manufacturer give you the temperatures which develop during this process and the relevant time periods?

Dear experts,
Please clarify our issue ie. In our case clad plate(SA 387 Gr.11
Cl.1+SS 304L), as per our customer spec.  Heat treatment of the clad
plate shall be as per applicable clad plate material specification
ie.SA 264 . But our clad plate manufacturer insists that for higher
thickness clad plates heat treatment is not required(ie.46,54,75Thk) &
for lower thickness he will perform heat treatment(ie.24&28Thk). So my
question is as per SA 264 is heat treatment is required or not for
clad plates after explosion bonding and if required which type of heat
treatment is required.
Please clarify my query & thanks in advance for your valuable feedback.
