Galvanized chains are not suitable for prolonged exposure to strong acid environments. The following is a detailed introduction of the points:
1. Zinc layer is sensitive to acidic media
The anti-corrosion ability of galvanized chains mainly depends on the surface zinc layer, which is extremely sensitive to strong acids. In acidic environments, especially in strong acids such as sulfuric acid, hydrochloric acid, nitric acid, etc., the zinc layer will rapidly undergo chemical reactions and dissolve, leading to the rapid loss of its protective effect.

2. After the zinc layer is corroded, it exposes the substrate
Once the zinc layer is corroded, the internal carbon steel material will be directly exposed to strong acid, which will quickly cause rust and structural damage, seriously affecting the strength, safety, and service life of the chain.

3. Galvanized chains are more susceptible to acid corrosion
Compared with hot-dip galvanizing, the zinc layer of electroplated galvanized chains is thinner and has weaker corrosion resistance. They are more susceptible to rapid corrosion in strong acid environments and are not suitable for any continuous or intermittent contact with acidic substances.

4. Not recommended for use in chemical or acid washing facilities
Galvanized chains are not suitable for environments with acidic vapors or liquids such as chemical plants, acid pickling workshops, electroplating workshops, etc. These places require higher grade corrosion-resistant materials, such as stainless steel chains (especially 316 grade) or specially coated chains.

5. The service life is greatly shortened
Even if exposed to strong acid environments for a short period of time, galvanized chains may quickly fail, unable to reach their normal working cycle, significantly increasing maintenance and replacement frequency, and increasing usage costs.
