Stainless Steel 304 / 316 Grades
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 per cent by weight and a high amount of chromium at approximately 18 to 20 per cent by weight. Other major alloying elements include manganese, silicon, and carbon. The remainder of the chemical composition is primarily iron. In most applications, steel is used where its corrosion resistance gives a long-lasting appearance and service life. The ease of cleaning and maintaining a hygienic surface on the steel makes 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, aluminium, 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 recommended for sea-side environments. They can be easily cleaned and resist organic chemicals and various 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 occasionally rinse your 316 Stainless Steel water tank with rainwater.
Stainless Steel Water Tanks FAQs
Are stainless steel water tanks better?
Stainless steel water tanks have several advantages that make them popular in specific applications. Here are some reasons why stainless steel water tanks are considered better in certain situations:
Beautiful stainless steel is a favourite material used by architects and designers of beautiful homes. Your Stainless Steel tank will maintain its appearance for its natural life.
Cost Effective Over its life cycle, a stainless steel water tank with a 30-year non-corrosion warranty will ultimately be very cost-effective.
Fire Resistant Scientists have found that stainless steel water tanks maintain their structural integrity and have only minor water loss when exposed to bushfires. We can fit our tanks with fire-fighting compliant fittings to meet local Council requirements.
Durability: Stainless steel is highly durable and corrosion-resistant, making it ideal for long-term water storage. It can withstand various weather conditions and is less likely to deteriorate over time than other materials like plastic or concrete.
Hygiene: Stainless steel is a non-porous material, so it does not harbour bacteria, mould, or algae growth. This makes it easier to maintain good water quality and reduces the risk of contamination.
Strength: Stainless steel has high tensile strength, making it less prone to structural failures or leaks. It is suitable for storing large volumes of water, particularly important in drier, lower rainfall areas and industrial or commercial applications.
Longevity: A Select Stainless Steel water tank has a minimum life expectancy of 30 years. The corrosion resistance properties of Stainless Steel means the tank will not only last for a long time but it will always look brand new.
Fully Recyclable Our stainless steel tanks have no plastic liners and they create a low carbon emission footprint in production. They are fully recyclable. The main mineral elements of stainless steel are highly valuable and can be easily recovered and re-used.
Do stainless steel water tanks rust?
Our stainless steel tanks have a 30 year non corrosion warranty. We recommend regular maintenance and care to ensure your tank is free from debris build up and given a rinse down with fresh water intermittently. In coastal areas, we recommend purchasing the marine grade [316] stainless steel option, as it is more suited to the marine environment.
What Grade Stainless Steel is best for Water Tank?
The best grade of stainless steel for a water tank depends on the application’s specific requirements. However, based on the information provided, here is a summary:
304 Grade Stainless Steel Tanks: Grade 304 stainless steel is commonly used for water tanks. It has a high nickel content (8-10.5%) and chromium content (18-20%), along with other alloying elements. Grade 304 offers good corrosion resistance and is suitable for most freshwater storage applications. It is easy to clean and maintain a hygienic surface, making it a popular choice for various purposes.
316 Grade Stainless Steel Tanks: Grade 316 stainless steel is an alloy that contains elements like chromium, nickel, molybdenum, and others. It offers enhanced corrosion resistance compared to 304 stainless steel. Grade 316 is particularly suitable for water tanks in sea-side environments.
Inland areas away from corrosive sea environments generally utilise 304 grade stainless steel tanks, while coastal or marine areas may benefit from the added corrosion resistance of 316 grade stainless steel tanks. Regular rinsing with rainwater can help maintain the passive film on 316 stainless steel tanks.
Ultimately, the choice between 304 and 316 grade stainless steel depends on factors such as the water conditions, location, budget, and the desired level of corrosion resistance. Consulting with experts or professionals familiar with local regulations can help determine the most suitable grade for your specific water tank application.
Does Stainless Steel Cost More?
On average, round stainless steel tanks made from Premium grade 304 stainless steel are approximately $500 to $1000 more than the equivalent tanks made from Aquaplate/Colorbond.
For example, a 10,000-litre round tank made from stainless steel is approximately $3295, whereas a similar one made from Aquaplate/Colorbond is approximately $2685.
The price differential is slightly more for slimline tanks because of the inclusion of internal stainless-steel rods to strengthen the slimline shape of the tanks.
The price differential is also greater if Marine grade 316 stainless steel is used to construct the tanks.
