Does soda lime glass bead blasting provide an adequate finish for corrosive service, as an alternative to pickling and what is the recommended surface profile range?
Whether or not a glass blasting will be sufficient for corrosive service will depend on the degree and nature of the oxidized surface and the corrosivity of the service, including the tendency of the medium to adhere to the surface of the steel. While a pickled surface provides corrosion resistance to the maximum capability of the grade, a thoroughly blasted surface may be sufficient and economical. Scale and heat tint for the duplex stainless steels are especially adherent and resistant to both mechanical and chemical removal.
