AISI 304 - Glass Blasting - Colour change
I appreciate your answers Our products are made by subsuppliers - I do not know everything about the processes. The surface is light grey after glassblasting The cleaning is performed at 55 °C, 5 minutes, pH about 9,0, the cleaning bath is also supposed to give some corrosion protection...- jesper1

AISI 304 - Glass Blasting - Colour change
I use glass blasted stainless steel (AISI 304) in the production. Unfortunately it sometimes turns dark (instead of stay grey/silver). After glass blasting the surface is cleaned (alkaline cleaning), the supplier claims it is passivated. Does anybody know the mechanisme of this colour change...- jesper1
