Steel has become one of the most used materials in a large number of industries. Not only has it gained importance in the construction sector, but it is now very common to see all kinds of instruments or tools made from this metal. This growth is due to its multiple characteristics, such as being 100% reusable and recyclable, its incredible durability and high resistance to a large number of adverse elements, among many other features it offers. However, the most commonly used alloy is stainless steel, used by different sectors such as the food and health sectors.
Importance of the finish on the surface of stainless steel
This type of steel is very easy to find in a large catalog of commercial and industrial products, which is why it is so important to pay attention to the wide variety of finishes it has. This element becomes relevant when we need a specific surface, not only for an aesthetic aspect, but for the corrosion resistance it can provide us.
For some retail items, such as: kitchen utensils, car ornaments, screws, among other elements. For various markets, it is important that the steel shines, although we might think that this is purely an aesthetic feature; however, it is not. For example, in kitchens, hotels and restaurants, having these shiny items greatly benefits hygiene and allows for better control of the quality of work offered to their customers.
Another case is in corrosive environments, such as a yacht or boat, where stainless steel with a smooth and smooth surface is used. Mainly, because this type of alloy is less susceptible to the accumulation of harmful agents for the metal, effectively preventing corrosion.
It is common for sanitary applications, the stainless steel must have an appropriate polish, not only to make it shine and look more aesthetic. In addition, it is essential that it favors the cleaning of the instrument, as these are elements that require delicate treatment in terms of hygiene.
What are the main finishes of stainless steel?
Remember that stainless steel is produced by combining elements such as: iron, chromium and other alloying structure elements, which produce a high resistance to corrosion. To classify them, the internal microstructure of each alloy is reviewed, which are a result of the elements present in that metal. Therefore, there is a great diversity of finishes, some can be obtained directly from a factory, while others need a more mechanical process in a specialized workshop.
It should be noted that there are standards that specify finishes that could be termed as standard. Among the most recurrent classifications is the ATSM, which is one of the most widespread among various industries. This is a general specification for the manufacture of plates, sheets and flat stainless steel strip, with laminated texture and that is highly heat resistant.
Learn about the most common types of stainless steel finishes
Finish 1: It has a matte gray appearance and tends to be very rough to the touch. It is a very common finish in laminated materials that have a hot manufacturing process, with the purpose of ensuring good corrosion resistance. It is then subjected to a heat treatment of annealing, recrystallization or solubilization. Subsequently, a special process of chemical pickling is carried out, where blasting is applied. This type of finish is given to all those materials that will undergo some subsequent transformation.
Finish 2B: It is the result of a cold rolling process. It has a bright and smooth finish, as a result of its annealing, pickling and the use of special rollers to give it a light lamination. Mainly, to give it a better appearance on the surface and provide the mechanical properties it needs. It is a common type of surface and ensures excellent corrosion resistance, as well as a perfectly smooth plane.
Finish P4: It has an intermediate polished appearance, with a linear textured finish. It is a special alloy that is obtained from a cold rolling process with a heat treatment, along with pickling and polishing processes with special sandpapers. It is a type of finish produced with mechanical action based on abrasive roughing. Normally, this type of finish on the metal is done using abrasive elements with grain 180-240.
