(OP)
The scale was eliminated months ago but one more time this scale has been found. The material is los alloy cladding 11/13 Cr and it has been treated in accordance with ASME VIII (750ºC, hold time 2 h).
This scale may affect to mechanical properties (Design Temperature 430ºC)

You lost me. Did you recently have to re-heat treat this material because of weld repair? If so, the material will re-oxidize as a result of exposure to 750 dig C for 2 hours in air. Normally, I would prefer light grit blasting or rotary scotch brite pads after all loose scale has been removed from the surface.

The best way to remove heat treat scale and tint from objects like this is to blast and then passivate with nitric acid.
For smaller all stainless parts you could pickle in mixed acid, but you don't want to do that on clad material
