The galvanized steel is one that receives a zinc coating, which enhances the corrosion protection. The cover can be added by dipping or electroplating:
Immersion: occurs when steel is dipped in hot liquid zinc. After this bath, the material is reserved in a special drying place. As it cools, zinc sticks to the steel, which is ready for use;
Electroplating: A process, that consists of dipping steel in an electrolyte bath, which coats the material and is transformed into zinc during drying.
Until and unless you know the main features of these two steels you cannot difference between galvanized and stainless steel.
Galvanized Steel: Features
Because it is more corrosion resistant and has better performance in contact with water, galvanized steel is widely used in construction, tooling, fencing, vehicle structures, utensils and household equipment. However, the material should not be used in all situations! Seawater and sea salt, for example, oxidize zinc faster, shortening its useful life. Therefore galvanized steel is not recommended for coastal areas and here comes the differentiation between galvanized vs stainless steel.
Galvanized Steel Rust?
As you can imagine that is galvanized steel rust proof or not, there are several methods of protection against corrosion of metals, one of the most efficient being galvanization. Galvanization is a process in which a piece of iron or steel is coated with metallic zinc.
Galvanized Steel and its Advantages
The galvanization process, as stated, is a chemical process that deposits a layer of zinc on the steel, which allows a long service life to the structure and increases its resistance against corrosion or rust and allows its fixation by screws. Zinc also helps to save natural resources such as iron ore as well as energy, which extends the shelf life of products that use protection and economically contribute to capital investment in steel.
And what is stainless steel?
Stainless steel is still mostly iron, but small amounts of other chemicals make all the difference in the alloy’s end result. The presence of chromium, manganese, carbon, silicon and in some cases nickel and molybdenum protects the iron by reacting with air and moisture instead, forming a thin layer of stable oxides / hydroxides that adhere to the workpiece surface., protecting her. Chromium is the main protector, a piece of stainless steel must contain at least 10% of metal.
Stainless steel is still mostly iron, but small amounts of other chemical elements make all the difference in the final consequence of the alloy. Chromium, manganese, carbon, silicon and sometimes nickel also give extra protection to the iron, which reacts with air and moisture, forming a thin layer of stable oxides / hydroxides that adhere to the surface of the material and protect it. Chromium is its main protector.
Uses of Stainless Steel
Robust and resistant, stainless steel is widely used in construction and plumbing. Industrial equipment is also made of this type of steel, as well as jewelry, furniture and cutlery. Unlike galvanized steel, it does not undergo any reaction due to contact with salt. Thus, it can be used in areas with sea air and in contact with seawater, being the ideal material for the installation of concertina in coastal regions.
Rusting Stainless Steel?
As we speak on stainless steel vs galvanized one, the composition of stainless steel may vary. Each with very specific characteristics and made for the production of various objects such as kitchen utensils, sinks and sinks for homes or industry – and other various applications.
Usually, stainless steel is made of a mixture of chrome and iron, and may present some flaws in microscopic locations which, in turn, are exposed to oxidation. In addition, it may also become more susceptible or not to rust, depending on temperature and exposure conditions. Therefore, the ideal is always to maintain maintenance and care on time.
