Stainless steel plates have similar resistance to general corrosion as unstable nickel chromium alloy 304. Long term heating within the temperature range of chromium carbide degree may affect the performance of alloys 321 and 347 in harsh corrosive media. Mainly used for high-temperature applications, which require materials to have strong resistance to sensitization to prevent intergranular corrosion at lower temperatures.

The corrosion resistance of stainless steel plates mainly depends on their alloy composition (chromium, nickel, titanium, silicon, aluminum, manganese, etc.) and internal microstructure, with chromium playing a major role. Chromium has high chemical stability and can form a passivation film on the surface of steel, isolating the metal from the outside, protecting the steel plate from oxidation, and increasing its corrosion resistance. After the passivation film is damaged, the corrosion resistance decreases.

Insufficient thickness of steel plates can easily bend, which will affect the production of decorative panels. If the thickness is too large and the steel plate is too heavy, it not only increases the cost of the steel plate, but also brings unnecessary difficulties to the operation. At the same time, it is also necessary to consider the allowance that should be left when processing or using stainless steel plates. There is no absolute consistency in the thickness of copper plates, but efforts should be made to ensure that the thickness of the same steel plate is as consistent as possible. Generally, for medium sized sawn plates, the thickness tolerance is 0.05-0.15mm. If the requirements are too strict, the grinding cost will also increase accordingly. Generally, steel plates with high tensile strength and hardness have greater mechanical damage resistance and longer durability, but the cost of grinding and processing is also relatively high.
