Stainless steel is a type of iron alloy that contains a certain percentage of chromium to give this material corrosion-resistant properties. Stainless steel storage tanks vary in shape and size depending on the amount of liquids or compressed gasses they have to store. The storage capacity of these tanks can range from few liters to thousands of gallons. The tanks that are used in industries have several inlets and outlets for easy mixing or blending of the products. The construction of stainless steel tanks can vary depending on the application these are used for.
