Will medical alcohol and edible alcohol cause harm to 304 stainless steel water cups?

Stainless steel water cups cannot hold acidic beverages. Acidity and alkalinity will cause corrosion of the inner wall of the 304 stainless steel water cup. Will medical alcohol and alcohol consumption cause corrosion damage to the stainless steel water cup?

First of all, let’s understand the composition of alcohol and 304 stainless steel. The main component of alcohol, alcohol, is an organic substance composed of three elements: carbon, hydrogen, and oxygen. It has the characteristics of evaporation and melting. At the same time, alcohol with higher concentrations will also produce chemical changes to metal materials, plastics, and plastics. 304 stainless steel is a practical 304 stainless steel. The main components are C≤0.08%, Si≤1.00%, Mn≤2.00%, 8%≤Ni≤15%, and 18%≤Cr≤20%. It has good characteristics and mainly reflects in formability and corrosion resistance.

If you simply master the composition of alcohol and 304 stainless steel, you will find that alcohol with a higher concentration is corrosive, while the content of medical alcohol is only 75%, and the content of food-grade plastic alcohol will be lower, so the difference between medical alcohol and food-grade plastic alcohol Corrosion will be almost zero. At the same time, the 304 stainless steel plate has good corrosion resistance, so medical alcohol and food-grade plastic alcohol will not cause corrosion to the inner wall of the 304 stainless steel water cup.
