Introduction to Stainless Steel Plates
Stainless steel plate is a kind of alloy steel that is not easy to rust. It is mainly made by adding a certain proportion of chromium to iron. When the chromium content reaches 10.5% or above, a dense oxide film will form on the surface of the steel. This film effectively prevents oxygen and water from further contacting the inside of the steel, thereby greatly improving its corrosion resistance. Stainless steel plates can be divided into austenite, martensite, ferrite and duplex stainless steel plates according to their organizational structure; according to their chemical composition, they can be classified into chromium stainless steel plates, chromium-nickel stainless steel plates, etc. Due to its excellent corrosion resistance, good plasticity and mechanical strength, stainless steel plates are widely used in many fields.
Introduction to galvanized steel plates
Galvanized steel plate is a composite material made by hot-dip galvanizing ordinary carbon steel plate. The main difference is the galvanizing process. Galvanizing is a method of preventing steel corrosion by using the active properties of zinc. Zinc is coated on the surface of the steel sheet to form a protective film to prevent the steel from being corroded by the external environment such as oxygen and water. Galvanized steel plate is mainly used in construction, automobiles, machinery and other fields, and has good corrosion resistance and ductility.
Stainless steel plates vs galvanized steel plates
1. Chemical compositionStainless steel plates are mainly alloy steels containing chromium, with a chromium content of at least 10.5%. Some types also add elements such as nickel and molybdenum. Galvanized steel plates are ordinary steel plates coated with a layer of zinc by hot-dip plating or electroplating. The substrate is mostly low-carbon steel, carbon structural steel or low-alloy steel. Different chemical compositions fundamentally determine their differences in performance and appearance.
2. Corrosion resistanceStainless steel plates can effectively resist corrosion from a variety of media such as air, water, acid, alkali, and salts by virtue of the dense chromium oxide protective film formed on the surface by chromium elements. Even in a relatively harsh environment, they can maintain a good condition for a long time. The corrosion resistance of galvanized steel plates mainly depends on the zinc layer on the surface. Under normal circumstances, the zinc layer can provide effective protection for the steel plate, but once the zinc layer is damaged, worn, or corroded and perforated, the steel plate will be directly exposed to the environment and easily rust and corrode.
3. Appearance DifferencesStainless steel plates can present a variety of colors and surface effects through different processing techniques, such as mirror-like bright luster, delicate matte texture, and rich colors through coloring. Galvanized steel plates are mostly gray or silver, and the surface usually has a unique zinc flower pattern, which is formed by zinc crystallization during the hot-dip galvanizing process. The surface of electro-galvanized steel plates is relatively smoother and flatter, with lower gloss.
4. Hardness and ProcessabilityStainless steel plates have high hardness, high strength, good toughness and wear resistance, but are difficult to process and require special tools and processes, such as laser cutting and plasma cutting. Galvanized steel plates have relatively low hardness and are not as strong as stainless steel, but they have good processing performance and are easy to cut, bend, weld and other processing operations, and can meet the processing needs of various complex shapes.
Summary and selection suggestions
Stainless steel plates and galvanized steel plates have obvious differences in chemical composition, corrosion resistance, appearance, hardness and processability. In practical applications, we need to make reasonable choices based on specific needs. If the application environment has extremely high requirements for corrosion protection, such as chemical industry, marine engineering and other fields, stainless steel plates are undoubtedly the better choice; if used in ordinary construction, home appliance manufacturing and other scenarios, they are more sensitive to cost and the processing technology requirements are relatively simple, galvanized steel plates can meet the needs at a lower cost.
In short, only by clarifying the requirements of the usage scenarios and weighing the material properties and costs can the most suitable materials be selected to maximize performance and benefits.
