JOINT ASME & AWS OCTOBER DINNER MEETING
(Abstract--Stainless
steel may turn orange, red, blue, or black in some pharmaceutical
waters. These rouge forms are iron oxides of different valences
and the associated water of hydration. The cause can be a
reaction of the water with the iron on the surface, corrosive ions,
temperature of the system, or deposition from external sources.
This presentation will discuss the three rouge classes, the mechanism
of formation, and the importance of passivation, why some castings
rouge and others don’t, why some heats of stainless steel rouge more
readily than others, why surface finish is important, and the role of
spray balls and water quality.)
