Even when stainless steel suffers any type of damage, be it a cut, dent or scratch, the oxygen in the air immediately combines with the chromium, forming the protective layer again and restoring its original resistance. Other elements added to stainless steel, such as nickel, molybdenum, vanadium and tungsten, can also be used to increase the material's resistance and guarantee the product multiple applications in different production sectors. Main attributes present in all Stainless Steel families Currently, hundreds of different stainless steel compositions are sold, manufactured using the most varied processing steps, which modify the properties of the metals, generating steels with diverse attributes. In this way, it is possible to classify stainless steels into five basic categories: Ferritic , Austenitic , Martensitic , Duplex and precipitation hardenable.

In this article, we will address the first three, which are those normally used in. The characteristics common to all stainless steel families are: High resistance to corrosion; Hygienic appearance; Ease Azerbaijan Phone Number of cleaning; Maintains its properties even when subjected to high or low temperatures; Resistance to sudden temperature variations and impacts; Surface finishes and varied shapes; Strong visual appeal (modernity, lightness and prestige); Favorable cost/benefit ratio; Low maintenance cost; Low surface roughness; Recyclable material. Ferritic Ferritic stainless steels are by far the most used types for the manufacture of equipment and household utensils, as they do not contain nickel in their composition, which significantly reduces the cost of production. Chromium is the main constituent of the ferritic alloy (between 11% and 20%), along with small additions of other ferrite stabilizers, such as silicon and niobium, in addition to containing less than 0.





AISI 430: the most used, due to its countless applications. It is widely used in the production of equipment for manufacturing nitric acid, car decorations, household items in general, such as tableware, stoves, refrigerators, sinks, cutlery. Minting of coins and telephone tokens, covering of elevators and refrigerated counters. AISI 439: used in the manufacture of elevator panels, sinks, heat exchanger tubes, domestic utilities, welded tubes, among others. AISI 443: has strong resistance to corrosion, especially against humidity and salt. Although most ferritic stainless alloys cannot compete with austenitic alloys in terms of durability, the high level of chromium in 443 steel makes it as corrosion resistant as 304. Furthermore, 443 steel, when compared to 304, expands even less with heat, which means less stress and less deformation.
