JOINT ASME & AWS OCTOBER DINNER MEETING


When: Tuesday, October 16, 2007

Where: Best Western Seven Seas in Mission Valley, 411 Hotel Circle South, San Diego, 92108

Subject: Contributing Factors to Stainless Steel Rouging in High Purity Water

(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.)
