Corrosive Effects of Chlorides on Metals

elements, such as nickel, niobium, molybdenum, and titanium. Nickel, molybdenum, ni obium, and chromium enhance the corrosion resistance of stainless steel. It is the addition of a minim um of 12% chromium to the steel that makes it resist rust, or stain 'less' than other types of steel.

Stainless steel corrosion by chloride ions?

Chloride is an excellent rust cause with a little damp air moisture. After your NaCl step, increase your rinsing via sprays (mist) or added tanks. A final warm water tank and blow dry step will significantly reduce the corrosion. The probable thing that allowed the corrosion to form was trace smearing of ferric iron in the manufacturing step.
