Stainless steel plates are a flat sheet made of stainless steel material. Stainless steel is an alloy material, mainly composed of iron, chromium, nickel, and other elements. Stainless steel plates have excellent corrosion resistance and mechanical properties that resist oxidation, corrosion, and high-temperature environments. It also has good strength, hardness, and ductility, making stainless steel plates widely used in a variety of applications.
Stainless steel plates are usually made by hot rolled process and stainless steel sheets are made by cold rolled process. They can be processed by cutting, bending, punching, and welding as required. Different stainless steel plates can be classified and selected according to their characteristics such as composition, surface treatment, and thickness.
Stainless steel plates are widely used in industries such as construction, chemical, food processing, medical equipment, automotive manufacturing, and aerospace. They are often used to make storage tanks, pipes, pressure vessels, decorative materials, kitchenware, tableware, medical equipment, body parts, etc.
Selection of applicable stainless steel raw materials, usually stainless steel billets obtained from the smelter. These billets are sent to the hot rolling mill for the next step after initial processing and quality inspection.
Stainless steel billets need to be preheated before entering the mill. The purpose of preheating is to improve the plasticity of the material and reduce the stress and resistance to deformation during the rolling process.
After preheating, the stainless steel billet enters the mill for the hot rolling process. Hot rolling is carried out at high temperatures, usually above 1000°C. The stainless steel billet is rolled and pressed continuously through a series of rolls and presses, gradually morphing into the desired thickness and width.
After hot rolled, the stainless steel sheet may have some internal stresses and changes in grain structure. In order to eliminate these problems, high-temperature treatment, such as annealing, is usually required. High-temperature treatment can improve the mechanical properties and grain structure of stainless steel sheets, making them more elastic and stable.
After hot rolled and high-temperature treatment, the stainless steel plates need to be properly cooled and leveled. The cooling process can be carried out by water cooling or air cooling to bring the plate to the required temperature and hardness. The leveling is done through processes such as roll pressing and stretching to make the stainless steel sheet meet the requirements of flatness and size.
After leveling, the surface of the stainless steel plates may have some roughness or oxides. In order to improve surface quality, pickling, polishing, passivation, and other treatments are usually carried out to obtain a bright and smooth surface.
Selection of applicable stainless steel raw materials, usually stainless steel blanks obtained from the smelter. After initial processing and quality inspection, these blanks are sent to the cold rolling mill for the next step of processing.
Stainless steel blanks are pickled to remove surface oxides and contaminants and then annealed. Annealing improves the plasticity and mechanical properties of the material and mitigates the effects of the subsequent cold rolled process on the material.
After pickling and annealing treatment, the stainless steel billet enters the cold rolling mill for the cold rolling process. Cold rolling is carried out at room temperature, where the stainless steel billet is gradually pressed to the desired thickness and width through a series of cold rolling rolls and pressures. During the cold rolling process, the material undergoes plastic deformation, which increases the hardness and strength of the material.
Depending on the requirements of the product, cold rolled stainless steel sheets may need to be galvanized or coated. Galvanizing increases the corrosion resistance of the stainless steel sheet, while coating provides additional protection and decorative effects.
After cold rolled, cold rolled stainless steel sheets need to be cut and leveled to achieve the required size and flatness. Cutting can be done by cutting machines or shears, while leveling is done by processes such as roll pressing and stretching.
The surface of cold rolled stainless steel sheets usually requires surface treatment to remove surface roughness and oxides. Common surface treatment methods include polishing, pickling, passivation, etc., to obtain a smooth and shiny surface.
Stainless steel plates are usually manufactured by hot rolled processes. Stainless steel plates have a greater thickness than stainless steel sheets, usually above 6mm, and can be tens of millimeters or even thicker. This greater thickness gives stainless steel plates many unique features and application advantages. First, the thickness of stainless steel plates increases their strength and stiffness, allowing them to withstand greater forces and loads for applications requiring structural strength, such as building structures, bridges, and pressure vessels. Secondly, thicker stainless steel plates have excellent corrosion resistance and durability to cope with harsh environments and chemical attacks. In addition, due to the greater thickness, stainless steel plates have better stability and plasticity during processing, allowing for a variety of machining and forming operations.
Stainless steel plates have high strength because of their manufacturing process and material properties. First of all, in the manufacturing process of stainless steel plates, advanced cold rolling or hot rolling process is used, through the processing and pressing of stainless steel raw materials, so that the plates obtain higher density and crystallinity, thus increasing their strength. Secondly, the material of stainless steel plates itself has good strength properties. Stainless steel is an alloy material composed of iron, chromium, and other alloying elements, where the addition of chromium makes it have excellent corrosion resistance and mechanical strength. In addition, stainless steel can be further adjusted to its strength and hardness by controlling the content and microstructure of the alloying elements. In addition, high strength stainless steel plates can also provide better resistance to shock and vibration, increasing the service life and reliability of the product.
Stainless steel plates have excellent corrosion resistance, which is one of the most important features for their wide application in many fields. The corrosion resistance of stainless steel plates is mainly attributed to the chromium element in its composition. Chromium reacts with oxygen to form a dense chromium oxide film, called a “passivation layer”, which covers the surface of stainless steel. This passivation layer is highly stable and corrosion resistant, effectively preventing oxygen, water and other corrosive media from further attacking the metal surface. In addition, the stainless steel added other alloy elements such as nickel, molybdenum, etc. can also enhance its corrosion resistance.
stainless steel sheets are generally produced through a cold rolled process. Stainless steel sheets are known for their relatively thin thickness. Compared to stainless steel plates, stainless steel sheets are typically between 0.3 mm and 6 mm thick. This thinner thickness gives stainless steel sheets a unique advantage in many applications.
The thinner thickness allows stainless steel sheets to be malleable and machinable. They can be easily bent, cut, and formed to accommodate a variety of complex design requirements. As a result, thin stainless steel sheets are widely used in manufacturing industries, such as automotive manufacturing, electronic equipment, home appliances, and decorative fields.
Stainless steel sheets have excellent bending properties and can be easily bent into various shapes, such as arcs, angles, U shapes, etc. At the same time, stainless steel sheets also have excellent deep punching properties, able to maintain high elasticity and plasticity during the stamping process, suitable for the manufacture of various shapes of parts and containers. Its good tensile properties make stainless steel sheets that can withstand large tensile forces without rupture, suitable for the manufacture of vehicle parts and mechanical parts. In addition, stainless steel sheets also have good formability and welding properties, can be complex shape forming and connection assembly through the forming process and welding methods.
Stainless steel sheets have an excellent surface finish, which is one of their unique features. During the manufacturing process, stainless steel sheets undergo multiple polishing and finishing processes, resulting in a very smooth, flat, and flawless surface. This highly polished surface not only enhances the appearance of stainless steel sheets but also makes them easier to clean and maintain.

Cutting and Bending: Stainless steel plates are processed using cutting and bending machinery to obtain the desired shape and size.
Stainless steel plates have high corrosion resistance, but rusting may still occur under certain conditions. The corrosion resistance of stainless steel is provided by the dense chromium oxide layer formed by the chromium element contained in it. This chromium oxide layer is able to react with oxygen in the air to form a stable oxide surface, which in turn prevents further oxidation reactions and thus acts as a protection against rust and corrosion.
However, when the chromium oxide layer on the surface of the stainless steel plates is damaged or contaminated, it will lead to rusting of the stainless steel plates. Common factors that lead to rust and corrosion of stainless steel plates include the following:
High Chloride Ion Environment: In environments with high chloride ions, such as seawater, salt water or chemicals containing chlorine, stainless steel may corrode and rust.
Strong Acids and Strong Alkalis: Certain strong acids and strong alkaline solutions can destroy the chromium oxide layer on the surface of stainless steel sheets, leading to rust and corrosion.
Mechanical Wear and Tear: Long-term mechanical wear or scratches may also lead to breakage of the chromium oxide layer on the surface of the stainless steel plate, which may cause rust corrosion.
In order to maintain the appearance and performance of stainless steel sheets, the following are some ways to maintain and clean stainless steel sheets:
Regular Cleaning: Use mild detergent and a soft cloth or sponge to clean the surface of the stainless steel sheet. Avoid using abrasives, metal brushes, or sharp objects to avoid scratching the surface.
Cleaners without Fluoride: Avoid cleaners with fluoride as they may cause spots on the stainless steel surface.
Cleaners without Abrasives: Choose cleaners without abrasives to avoid scratching the stainless steel surface.
Rinse with Clean Water after Cleaning: After cleaning the stainless steel sheet, rinse the surface with clean water to ensure that the cleaner is completely removed to avoid leaving residue.
Dry and Wipe: Dry the stainless steel plate with a clean, soft cloth to prevent water stains and scale.
Avoid Using Acidic Cleaners: Avoid using acidic cleaners as they may have a corrosive effect on the stainless steel surface.

304 stainless steel sheet and 304L stainless steel sheet are very similar in chemical composition, with the main components being chromium (Cr) and nickel (Ni), and both are 18-8 type stainless steels. However, they differ in their carbon content, which leads to some differences.
Carbon Content: 304 stainless steel sheet generally has a carbon content of 0.08% or less, while 304L stainless steel sheet has a lower carbon content, generally below 0.03%. This makes 304L have better corrosion resistance, especially when welding, to reduce the risk of intergranular corrosion.
Corrosion Resistance: Because of its low carbon content, 304L stainless steel sheet is more resistant to the tendency of intergranular corrosion during welding, so it is more commonly used in some special environments, such as chemical, medical and food processing, to improve corrosion resistance.
Apart from the above differences, 304 and 304L stainless steel sheets are almost identical in terms of physical and mechanical properties. Therefore, when choosing which material to use, the decision can be based on the specific application environment and requirements. If better corrosion resistance is required, especially in the case of welding, 304L stainless steel sheet can be chosen.
304 stainless steel sheet and 316 stainless steel sheet are two common stainless steel materials, which have some differences in chemical composition, corrosion resistance and mechanical properties.
Chemical Composition: 304 stainless steel plate contains about 18% chromium (Cr) and 8% nickel (Ni), while 316 stainless steel plate contains about 16-18% chromium and 10-14% nickel, in addition to 2-3% molybdenum (Mo). The addition of molybdenum makes 316 stainless steel superior to 304 stainless steel in terms of corrosion resistance.
Corrosion Resistance: 316 stainless steel sheet has better corrosion resistance than 304 stainless steel sheet, especially for corrosive media such as chlorides. Therefore, 316 stainless steel is often used in marine environments, chemical equipment and food processing, etc., where high corrosion resistance is required.
Oxidation Resistance: 316 stainless steel sheet has better oxidation resistance in high temperature environment because the presence of molybdenum helps to improve oxidation resistance.
Strength and Hardness: Due to the presence of molybdenum in 316 stainless steel sheet, it is slightly better than 304 stainless steel sheet in some mechanical properties, with higher strength and hardness.
