The use of stainless steel in application has been extremely common due to its attractiveness and durability. In many applications, stainless steel can be effectively used to reduce the risk of corrosion and improve the appearance of any environment or application. Corrosion in general is one of the most common forms of aging of any material or structure. This type of corrosion can vary from a type of discoloration or oxidation to a physical breaking down of the material over time. Stainless steel is known to be very resistant to corrosion in many different environments and can typically last much longer than more traditional materials.

When considering the use of stainless steel in applications where there is a risk of corrosion, one of the most important factors to consider is the type of stainless steel. Different types of stainless steel are available with different corrosion resistance ratings. This means that certain types of stainless steel are more appropriate for certain environments and applications than others. In order to determine the right type of stainless steel for a particular application, it is important to understand the corrosive environment in which the stainless steel will be used.

One type of corrosion that stainless steel can be used to prevent is crevice corrosion. Crevice corrosion is caused by the presence of oxygen and water within confined spaces between two surfaces. This type of corrosion is particularly dangerous because it can occur even within sealed structures and can even reach to areas that are impossible to reach using traditional cleaning and prevention techniques. The use of stainless steel can reduce the risk of crevice corrosion by providing an oxygen barrier between the two surfaces and eliminating the possibility of water infiltration.

In addition to choosing the right type of stainless steel for a particular application, the installation of the stainless steel material is also critical. Proper installation is essential to ensure that the stainless steel element is able to perform optimally and to provide the best corrosion resistance. Proper installation techniques involve closely following manufacturers instructions, as well as taking into account any potential environmental issues or crevices that may exist within the surrounding environment.

In summary, the use of stainless steel in applications can be a very effective way of reducing the risk of corrosion and improving the appearance of any environment or application. When selecting stainless steel for a particular application, it is important to consider the type of stainless steel, the type of corrosive environment, and the installation techniques that will be used. Taking these factors into account can help ensure that the stainless steel element is properly installed and is able to perform optimally and provide the best corrosion resistance.

Gap Corrosion and Selection of Stainless Steel

Gap Corrosion occurs when two dissimilar metals are connected together in the presence of an electrolyte. When this occurs, electrolytic cells are formed at the contact point of the two metals, resulting in corrosion at the junction of the two different materials.

When it comes to choosing the right type of stainless steel for your application, it is important to know what types of corrosion you may be facing. Corrosion resistance is dependent on the type of stainless steel and the alloying elements that have been added. The alloying elements in the various grades of stainless steel are what give it the specific properties such as resistance to corrosion. Certain grades are better for certain applications, so it is important to research and select the appropriate grade for the product.

Types of stainless steel that have been specifically designed to prevent corrosion due to gap corrosion include austenitic stainless steel (Grade 304, 316, 321 and 347) and Duplex stainless steel (2205 and 330). These types of stainless steel are made with a combination of chromium, nickel, molybdenum, and nitrogen which increases the corrosion resistance. In particular, Duplex stainless steel grades have a higher corrosion resistance and are better suited for environments where gap corrosion is a concern.

When selecting stainless steel for gap applications, it is important to consider both the grade of stainless steel and the environment in which it is used. It is also important to ensure that the stainless steel is mechanically and chemically compatible with the other materials being used in the application. By selecting the right stainless steel for your application, you can increase the reliability and lifetime of the product.
