If there is visually a strong corrosion of the pistons.

At the end of the test, a value between 0 (no corrosion) and 5 (very severe corrosion) is given.

The spout has heavy corrosion, the valve handles are scratched with some pitting.

Baking soda (optional--if heavy corrosion is present on the battery terminals)

the valves involved in the acetic acid manufacturing process have to resist to severe corrosion

Strong corrosion protection can be achieved.

High strength and high resistance to heat and corrosion.

The valve has good biological performance and strong corrosion resistance.

Accordingly, it has high corrosion resistance under a high temperature and a high humidity environment.

It does not use any strong acid or strong base causative of apparatus corrosion.

If there is visually a strong corrosion of the pistons.

It is highly resistant to various forms of corrosion

Advantageously, the deposited coatings exhibit high corrosion resistance, high wear resistance, and excellent structural properties.

8) Acid and alkali chemical corrosion is not afraid of most strong acids, alkalis, salts

Excellent resistance to corrosion and long service life.
