Welding 316L or 304L manifolds by argon arc or laser leaves an oxide scale of Fe3O4, Cr2O3 and chromium spinel plus a chromium-depleted zone that threatens corrosion resistance and leak reliability, and nitric plus hydrofluoric pickling removes oxides fast while over-pickling welds gray and coarse and leaving residue in long narrow channels. A two-step route loosens oxid...
