SUS316 Stainless Steel Sheet For Tanks
Leave a message
If you are looking for highly corrosion-resistant SUS316 stainless steel sheets suitable for chemical and food-grade storage tanks, Gnee offers comprehensive material specifications, consistent quality, and global delivery capabilities. Our 316/316L stainless steel sheets for tanks have excellent resistance to chloride corrosion and are widely used in industries such as chemical storage tanks, food tanks, pharmaceutical containers, seawater desalination equipment, and pressure vessels.
Why Choose SUS316 Stainless Steel Sheet for Tanks?
Our 316 stainless steel corrosion-resistant sheet contains 2.0–2.5% Mo (molybdenum), offering superior resistance to chloride corrosion, pitting, and crevice corrosion compared to 304. It is ideal for water treatment tanks, brine tanks, and chemical storage tanks. With a long-term operating temperature up to 600°C, it can be used in heated tanks, steam tanks, and other applications. 316 hot-rolled stainless steel sheet is easy to weld, bend, and roll, suitable for processing large vertical/horizontal storage tanks. Furthermore, it is available in various finishes including No.1, 2B, BA, and Mirror 8K, suitable for the food and pharmaceutical industries.

Is SUS316 stainless steel suitable for water tanks?
316 stainless steel contains molybdenum, making it more resistant to corrosion from chlorides and other oxidizing agents than 304 stainless steel. This is crucial for the long-term safety of water tanks, especially in complex aquatic environments. 316 stainless steel is food-grade and suitable for storing drinking water, ensuring water quality safety and preventing secondary contamination.
What is the thickness of 316 stainless steel used in water tanks?
The thickness of 316 stainless steel used in water tanks varies considerably, ranging from 1.5 mm to over 15 mm, depending on the tank's size, application, and pressure requirements. Small water tanks for low-pressure applications may use thinner wall thicknesses (1.5-3 mm), while larger tanks or those with pressure requirements use thicker walls, typically thicker at the bottom than at the top. For example, a small domestic water tank might have a wall thickness of 1.5 mm, while a medium-sized industrial water tank might have a top wall thickness of 5 mm and a bottom wall thickness of 8 mm.
