3 Causes Of Corrosion Of Stainless Steel Tubes

While stainless steel can resist corrosion better than carbon and steel alloys, certain conditions can affect the integrity of the material over time. For example, as it comes in contact with an electrolyte such as water, oxygen, or other metal, it causes a chemical reaction, due to which it can lose electrons and become weak. Hence, it renders the stainless-steel product vulnerable and can succumb to rust, cracks, and holes, due to which it can collapse.

Stainless steel corrosion is of different types. Uniform corrosion spreads evenly across the surface of stainless steel material and causes a uniform metal loss across the entire surface. Pitting corrosion is a form of localized corrosion occurring in a confined area in pits and spots due to exposure to aggressive chemical species like chloride, which can cause oxide breaks on the metal. Finally, crevice corrosion in stainless steel occurs in the microenvironment where there is a difference in ion concentration between two metal areas.

Intergranular corrosion is a form of selective attack in the vicinity of grain boundaries in stainless steel. It can severely affect the mechanical properties of the metal. Tensile stress and a specific corrosive environment can also crack stainless steel and can result in axial cracks in the pipeline. The fine cracks may emerge in the microstructure of the metal, and hence it is hard to spot.

To prevent the metal integrity of your 416 stainless steel tube and other stainless steel grades, you need to protect the metal against these corrosive atmospheres that can critically affect its lifespan.


The chromium content of stainless steel alloys is vulnerable to chlorides. In wet and humid environments that contain chloride ions, it can cause pitting corrosion and crevice corrosion in the stainless steel tubes. Chloride breaks down the passive film on the surface of stainless steel. Corrosion accelerates in an alkaline environment and coastal areas with salt-spray exposure, resulting in the rusting of the metal.


While stainless steel is resistant to acidic corrosion, strong acids can destabilize the passive layer on the stainless steel surface. Intermediate concentrations of sulfuric acid and hydrochloric acid can cause surface corrosion. These are strong reducing acids and, when present in higher concentrations, can trigger the degradation of stainless steel.

Iron And Carbon Steel Particles

Iron and carbon steel particles can deposit on the surface steel and damage the oxide layer. At the site of contamination, it can produce localized or pitting corrosion. The rust spots can compromise the chromium oxide surface of the stainless steel tubes. Carbon contamination of stainless steel can occur due to the breakdown of organic materials when exposed to materials from nearby welding, combustion of sooty gas flames, or because of paint, pen, or pencil markings.

To Conclude:

To ensure the longevity of your stainless steel tubes, you need to protect and prevent contact with corrosive substances. Stainless steel requires minimum maintenance, and following the best practices, keep the integrity of the protective covering of stainless steel intact to avoid any form of rusting in various environments.

5 Tips For Cleaning Stainless Steel Tubes

Stainless steel tubes require cleaning at regular intervals for effective maintenance of their integrity.You can educate about the signs of contamination, corrosion, and surface degradation of stainless steel to determine what degree of cleaning and care it requires.To establish the best cleaning criteria, you need to identify the scope and objectives of your cleaning process by carefully inspecting the stainless steel tubes. Accordingly, you need to deploy the best cleaning practices that adhere to the industry standards defined for the custom-built stainless steel tubes.

The surface of stainless steel tubes has a thin layer of chromium oxide which protects the metal from corrosion. The alloy’s chromium content combines with oxygen from the atmosphere to form the passive layer of chromium oxide. Various contaminants can get trapped within the passive film and can severely affect its corrosion resistance properties. Hence, stainless steel products require regular cleaning to prevent corrosion and protect the luster of the surface.

The various types of pipe contamination for 316 stainless steel tubes and other grades are dirt, iron contamination, deposition of oil, paint, grease, and rust. For cleaning stainless steel tubes, you can refer to the following.

Routine Cleaning

To carry out routine cleaning of stainless steel tubes, you can clean them with soap, mild detergent, or ammonia solutions in warm water. You can apply any of these agents with a soft cloth or nylon sponge. After this, you need to rinse and dry it with a soft cloth. It helps to remove ordinary soiling. While cleaning stainless steel, use mild non-scratching abrasive powders, and avoid using standard carbon steel brushes or steel wool. It can leave articles embedded on the surface, which can trigger rusting.

Solvent Cleaning

You can use organic solvents to remove stains that are fresh and have not yet oxidized or decomposed. The solvent should not contain chlorine, like acetone, methyl alcohol, and mineral spirits. You can immerse smaller articles into the solvents or use the vapor cleaning method to control the discharge of solvents. Wipe it post-cleaning.

For Moderate Soiling

You can use a mild abrasive cleaner for moderate soiling and light staining and use a soft cloth, nylon scouring pad, or a soft bristle brush. In the direction of the polished finish, use the material to make long, even strokes. You need to avoid using a circular rubbing action. After you clean it, you need to rinse and dry-wipe to complete the process and remove water stains.

For Heavier Soiling

For more intense staining and heavy soiling, you can use ammonia solution or warm/hot detergents. You can also use acidic cleaners and follow the cleaning procedures mentioned for moderate soiling.

Passivating Treatment

To maximize the corrosion resistance capability of stainless steel and remove surface contaminants, you can use the passivation treatment. First, you need to clean the stainless steel surface thoroughly and remove the pollutants. After this, you need to enter the metal in a passivating acid bath. Depending on the chromium content and the machinability properties of the stainless steel grade, the nature of the passivation treatment will vary.

To Conclude:

While selecting the cleaning practices for stainless steel tubes, you need to carefully analyze the potential of the cleaning agent to counter the contamination or corrosion. Proper routine care can extend the lifespan of stainless steel.
