Available in 2 grades of Stainless Steel – 304 Grade and 316 Grade:
304 Grade Stainless Steel
Grade 304 stainless steel is generally regarded as the most common austenitic stainless steel. It contains high nickel content that is typically between 8 and 10.5 percent by weight and a high amount of chromium at approximately 18 to 20 percent by weight. Other major alloying elements include manganese, silicon, and carbon. The remainder of the chemical composition is primarily iron. In most applications the steel is used where its corrosion resistance gives long lasting appearance and service life. The ease of cleaning and of maintaining a hygienic surface on the steel make it excellent for many purposes.
Our 304 Grade is a good choice if you live inland away from the salt corrosive sea.
316 Grade Stainless Steel
Grade 316 Stainless Steel is a metal alloy, made up of steel mixed with elements such as chromium, nickel, molybdenum, silicon, aluminum, and carbon. Iron mixed with carbon to produce steel is the main component of stainless steel. Chromium is added to make it resistant to rust.
Water tanks made from Grade 316 are perfect for sea-side environments. They can be easily cleaned, resists organic chemicals, and a wide variety of inorganic chemicals.
Here’s a tip! Fresh water and air react with the chromium oxide compound that forms a passive layer over the steel, if damaged the passive film reconstitutes itself. So make sure you give your 316 Stainless Steel water tank an occasional rinse with rainwater.
