Advantages of stainless steel signage:

1. Does stainless steel have good welding performance?

2. Corrosion resistance of stainless steel: The vast majority of stainless steel products require good corrosion resistance. When the number of chromium atoms in steel is not less than 12.5%, it can cause a sudden change in the electrode potential of the steel, rising from negative potential to positive electrode potential. It can prevent electrochemical corrosion.

3. Heat resistance: Heat resistance refers to the ability of stainless steel to maintain its excellent physical and mechanical properties at high temperatures.

Stainless steel has a metallic texture; Stainless steel has a high-end feel; Stainless steel has a lighter weight; Stainless steel has a strong sense of weight; Stainless steel has a strong three-dimensional feel, and stainless steel has a brushed and glossy surface.

Disadvantages of stainless steel signage:

Stainless steel is a stable chromium rich oxide film (protective film) formed on its surface, which is extremely thin and sturdy. Prevent oxygen atoms from continuing to infiltrate and oxidize, thereby obtaining rust resistance. Once for some reason, this thin film is constantly damaged, and oxygen atoms in air or liquid will continuously separate out, forming loose iron oxide, and the metal surface will also be constantly corroded. During the manufacturing process, there may be damages, defects, and substances that affect the appearance, such as dust, floating iron powder, or embedded iron, which have the potential to damage the oxidation protective film. Once the protective film is damaged, thinned or otherwise altered, the stainless steel below will begin to corrode.
