Calcium Chloride 77.5% 250g 5060405297462 | eBay
Calcium chloride, CaCl2, is a salt of calcium and chloride. It behaves as a typical ionic halide, and is solid at room temperature. Because of its hygroscopic nature, anhydrous calcium chloride must be kept in tightly sealed, air-tight containers.

TB-0909 — How DCI® works | Resource | GCP Applied …
Even as corrosion begins (at a chloride concentration much higher than in concrete without calcium nitrite), corrosion rates will be lower than the rates on unprotected steel when corrosion began. The reservoir of DCI® surrounding the steel continues to inhibit corrosion, even though it has now been overpowered by the chloride ions.

Corrosion resistance properties of monel alloy 400
Monel nickel-copper alloy K-500 coines the excellent corrosion resistance characteristic of Monel alloy 400 with the added advantages of greater strength and hardness. The increased properties are obtained by adding aluminum and titanimum to the nickel-copper base, and by heating under controlled conditions so that submicroscopic particles of Ni3 (Ti, Al) are precipitated thoughout the matrix.

How to prevent corrosion damage in swimming pool …
The environment of an indoor swimming pool is aggressive, due to both the temperature, humidity in the air and the chemicals added to the water. This is why it is very important that the materials used in a dehumidifier are protected against corrosion.
Corrosion resistance properties of Monel alloy 400
Monel alloy 400 is not subjected to stress corrosion cracking inthe chloride salts and it offers superior resistance to the whole non-oxidizing halides. 1. Neutral and Alkaline Salts like chlorides, carbonates, sulfates, nitrates and acetates have minor effect on Monel alloy 400.
