SS 304L ASTM 8mm 10mm Small Stainless Steel Rectangular Pipe
Types of Stainless Steel corrosion
There are six common types of corrosion of this metal. Each one of them will depend on the environment the piece was exposed to and how you maintain it.
General: this type of corrosion is a uniform loss of metal on the surface. This occurs over time and if your jewelry has a pH value of less than 1.
Galvanic: this one is also called bimetallic corrosion and it occurs with electrochemical processes. This is when one metal corrodes more in comparison to another when there is a presence of electrolytes. However, this one is less likely to occur through your daily routines.
Intergranular: with this type of corrosion, boundaries of crystallites are more likely to corrode than the inside surfaces of a piece. It occurs if your stainless steel is exposed to high temperatures, approximately 842-1562 degrees Fahrenheit. But, this is another situation that is less likely to occur during your regular day.
Pitting: pitting is localized corrosion that occurs in cavities or holes of your jewelry. This one occurs when your pieces are exposed to chlorine, so don’t wear your stainless steel jewelry when at the pool.
Crevice: another one that is localized, crevice corrosion occurs at the crevice between two joining surfaces on your jewelry. It can be formed between two metals, and even between metal and non-metal.
Stress corrosion cracking: this corrosion refers to growth of crack formation in a corrosive setting. This means that tensile stresses when combined with the corrosive environment which leads to cracking.
