The use of stainless steels stems from the need to produce components that offer not only reliability and functionality, but also long-term durability. This characteristic gives the products a high intrinsic value and significantly reduces maintenance costs.
One of the main metallurgical transformations involves the addition of nickel in percentages greater than 7%, which converts the ferritic structure of steel into an austenitic structure. Among other things, this change results in a marked magnetic difference: stainless steels are generally non-magnetic or weakly magnetic, unlike many other iron-based alloys.
Often associated with qualities such as nobility, cleanliness and strength, stainless steels are particularly valued for their ability to resist corrosion. However, this property is not uniform for all types. Some types, for example, are vulnerable to chlorides and are not suitable for applications in sanitary environments or in the presence of salt water, such as swimming pools.
From a mechanical point of view, these materials offer excellent performance: high strength, hardness and toughness. In addition, specific surface treatments can be used to achieve high-quality finishes with glossy, reflective or decorative effects. Austenitic stainless steels, in particular, are also suitable for use in extremely low temperatures.
Stainless steel is used in a wide range of sectors: from domestic to automotive, from architecture to construction, including the chemical industry, medical technology, the environment, the marine sector and transport.
At the end of their life, stainless steel products are sorted, recycled and remelted, creating new reusable material in a virtuous cycle that contributes to sustainability.
Finally, it should be noted that stainless steels are highly resistant to numerous aggressive agents: organic and inorganic acids, saline solutions and alkaline substances, as well as the effects of atmospheric agents.
