1. What is Stainless Steel Plate?
Stainless steel plates have a smooth surface, high plasticity, toughness, and mechanical strength. They are resistant to corrosion from acidic, alkaline gases, solutions, and other media. It is an alloy steel that does not rust easily, but it is not absolutely rust-proof. Stainless steel plates refer to steel plates that are resistant to the corrosion of weak media such as atmosphere, steam, and water. In contrast, acid-resistant steel plates refer to those that are resistant to the corrosion of chemically corrosive media such as acids, alkalis, and salts. Stainless steel plates have been around since the early 20th century and have a history of over a century.
2. Classification of Stainless Steel Sheets
(1)By microstructureAustenitic stainless steel plates, Martensitic stainless steel plates (including precipitation-hardened stainless steel plates), Ferritic stainless steel plates, and Duplex stainless steel plates (a combination of austenitic and ferritic).
(2)By main chemical composition or characteristic elements in the steel
Chromium stainless steel plates, Chromium-nickel stainless steel plates, Chromium-nickel-molybdenum stainless steel plates, Low-carbon stainless steel plates, High-molybdenum stainless steel plates, and High-purity stainless steel plates.
(3)By performance characteristics and uses
Nitric acid-resistant stainless steel plates, Sulfuric acid-resistant stainless steel plates, Pitting corrosion-resistant stainless steel plates, Stress corrosion-resistant stainless steel plates, and High-strength stainless steel plates.
(4)By functional characteristics
Low-temperature stainless steel plates, Non-magnetic stainless steel plates, Easy-to-machine stainless steel plates, and Superplastic stainless steel plates. The commonly used classification method combines the microstructural characteristics of the steel plates with their chemical composition, generally dividing them into Martensitic stainless steel plates, Ferritic stainless steel plates, Austenitic stainless steel plates, Duplex stainless steel plates, and Precipitation-hardened stainless steel plates, or into two major categories: Chromium stainless steel plates and Nickel stainless steel plates.
Typical uses include equipment for pulp and paper, machinery, dyeing equipment, film developing equipment, pipelines, and materials for external use in coastal areas.
3. Characteristics of Stainless Steel Plates
(1) Corrosion ResistanceStainless steel plates have similar capabilities to resist general corrosion as the unstable nickel-chromium alloy 304. Prolonged heating in the temperature range of carbide chromium may affect the performance of alloys 321 and 347 in harsh corrosive media. They are mainly used for high-temperature applications, which require strong resistance to sensitization to prevent intergranular corrosion at lower temperatures.
(2) High-Temperature Oxidation Resistance
All stainless steel plates possess high-temperature oxidation resistance, but the rate of oxidation can be influenced by the exposure environment and the inherent characteristics of the product form.
(3) Physical Properties
The overall heat transfer coefficient of a metal depends not only on the metal's thermal conductivity but also on other factors. In most cases, these are the film heat dissipation coefficient, rust scale, and the surface condition of the metal. Stainless steel can maintain a clean surface, thus its heat transfer is better than that of other metals with higher thermal conductivity.

(5) Requirements for Selecting Stainless Steel Plates
When selecting stainless steel plates, consider the operating conditions, such as manual or automatic operation, the performance and type of press machines, and the quality requirements for the pressed materials, such as hardness and luster. Economic considerations are also important; each newly ground steel plate should be able to produce a certain number of high-quality decorative panels.Furthermore, when choosing the most appropriate thickness of the steel plate, consider its service life, quality, rigidity, and the strength requirements when the plate is under pressure; thermal conductivity; the distribution of pressure, and the size of the plate.
If the steel plate is not thick enough, it is prone to bending, which will affect the production of decorative panels. If the thickness is too great, the steel plate becomes heavier, which not only increases the cost of the steel plate but also brings unnecessary difficulties to the operation. It is also necessary to consider the allowance that should be left during the processing or use of the stainless steel plate. The thickness of copper plates is not absolutely uniform, but it is strived to be as consistent as possible within the same sheet of steel plate, with a general thickness tolerance of 0.05 to 0.15 millimeters. If the requirements are too strict, the grinding costs will also increase accordingly. Generally, the greater the tensile strength and hardness of the steel plate, the greater the resistance to mechanical damage, the longer the service life, but the grinding and processing costs are also higher.

4.How to set up stainless steel plates?
(1)How to Make the Skeleton?There are two types of skeletons: wooden structure and steel structure. The wooden structure skeleton is made of square wood, and the steel structure skeleton is welded by square tubes and angle irons.
(2) Fixing of Base Board
The function of the base board is to ensure the flatness of the board and facilitate the attachment of decorative panels. Plywood, wood board or density board is used indoors, and OSB waterproof European pine board is used outdoors. The base board is directly fixed to the steel frame with steel nails or screws. Then apply structural adhesive to the base plate and stick the stainless steel plate on it.
When fixing the base board, leave a gap of about 2cm between the boards. The gap is to facilitate left and right adjustment when attaching stainless steel. Stainless steel needs to be folded up, down, left and right.
(3) Installation of Colored Stainless Steel Decorative Panels
Colored stainless steel plates are usually installed and fixed by adhesive bonding or nailing. Welding is not suitable because the high temperature of welding will destroy the colored coating on the surface and affect its appearance.
