Feb 03,  · Stainless steel corrosion, also known as “rouge,” describes a variety of discolorations to the surface. The color depends on the amount of oxygen to which the surface is exposed. Inside steam lines corrosion will typically be black, while corrosion on an autoclave chamber is more commonly a red-brown color on the walls.

Whether for the consumer market or industrial use, one of the most popular reasons for choosing stainless steel is its corrosion-resistant properties.

The stainless steel corrosion inhibitor is composed of a solute and a solvent, wherein the solvent refers to deionized water, and the solute refers to SDBS ( 

The following are common forms of specialized corrosion. 1. Galling. This corrosion occurs when stainless steel parts are forced together. Commonly seen with nuts, bolts, and other fasteners, corrosion isn’t visible until the parts are separated or disassembled. The process uses repeated passes to adjust the dimensions of the steel slowly.

Stainless Steel Corrosion & Discoloration (-----) 2002. I have a 316 SS tank tank that was blackened by a low pH DDBSA (Dodecyl Benzene Sulfonic Acid) that I would like to bring back to its natural color. What's the best way to do this? Also, how much harm does 25% NaOH liquid do to a 304 SS tank if stored (hauled) for short periods of time

Pitting Corrosion on stainless steel. The passive layer on stainless steel can be attacked by certain chemical species. Chloride ion is the most common of these and is found in everyday materials such as salt and bleach. Harsh pitting corrosion is a localized damage that eats pits into stainless steel. In addition to chloride ion, can be caused

Stainless steel corrosion resistance is a result of a very thin (about 5 nm) oxide layer on the steel's surface. This oxide layer is referred to as a passive layer since it renders the surface electrochemically passive in the presence of a corrosive environment. The passive layer forms because of the chromium added to stainless steel.
