The corrosion resistance of stainless steel plate mainly depends on its alloy composition (Cr, Ni, Ti, Si, Al, Mn, etc.) and internal structure. The main role is chromium. Chromium has high chemical stability. It can form a passive film on the steel surface, isolate the metal from the outside world, protect the steel plate from oxidation, and increase the corrosion resistance of the steel plate. After the passivation film is destroyed, the corrosion resistance decreases. Now let's take a look at it.

l How to choose stainless steel plate?
It is a kind of alloy steel that is not easy to rust, but not rust-free. Stainless steel plate refers to the corrosion-resistant steel plate in weak media such as atmosphere, steam, and water, while acid-resistant steel plate refers to the corrosion-resistant steel plate in a chemical corrosive medium such as acid, alkali, and salt. All stainless steel plates have high-temperature oxidation resistance, but the oxidation rate is affected by inherent factors such as exposure environment and product morphology.
First of all, stainless steel has corrosion resistance, it can resist general corrosion similar to the unstable nickel-chromium alloy 304. Long time heating in the temperature range of chromium carbide degree may affect the corrosion resistance of alloys 321 and 347 in the severe corrosive medium. It is mainly used in high-temperature applications. High-temperature applications require strong sensitization resistance to prevent intergranular corrosion at lower temperatures. This is one of the reasons why stainless steel will not rust for a long time. Secondly, stainless steel has high-temperature oxidation resistance, and most stainless steels have high-temperature oxidation resistance. However, the oxidation rate will be affected by inherent factors such as exposure environment and product morphology.
The selection of stainless steel plate should consider the operation conditions, such as manual operation or automatic operation, the performance and type of hot press, and the quality requirements of pressed materials, such as hardness and luster. Also consider the economic accounting, each time the new polished steel plate, requirements can produce a slow quality decorative plate times. In addition, when selecting the most reasonable thickness of steel plate, the service time, quality and stiffness should be considered, and the strength requirements of the plate under compression should be considered; Thermal conductivity; The distribution of pressure, and the format of pressing plate.
The stainless steel plate has a smooth surface, high plasticity, toughness, and mechanical strength, and is resistant to corrosion of acid, alkaline gas, solution, and other media. Foshan TaiYuDa Steel Group Co., Ltd. developed a variety of stainless steel plates and carried out a large number of tests before leaving the factory. This kind of stainless steel plate is not only of high quality but also of good price. If you are engaged in the stainless steel plate business, you can consider using our cost-effective products.
