What is the Difference Between 304 Stainless Steel and 316 Stainless Steel?

The globally accepted steel standard for Stainless Steel products is 304 Steel quality. In vacuum flasks, 304 stainless steel quality is generally used.

The high levels of chromium and nickel found in both 304 and 316 stainless steels give them strong resistance to heat, wear, and corrosion. They are known not only for their resistance to corrosion but also for their clean appearance and overall hygiene.

Both types of stainless steel are encountered in a wide range of industries. The most common stainless steel quality, 304, is considered the standard “18/8” stainless. 304 stainless steel is widely used because it is durable and easy to shape into various forms such as stainless steel sheets, rods, and pipes. The resistance of 316 steel to chemicals and marine environments makes it a popular choice among manufacturers.

The steel quality used in 316 Stainless Steel thermoses is more costly and is considered a premium product in the market due to its longer-lasting heat and cold retention properties. When comparing the prices of raw materials, the raw material for 316 Stainless Steel is 40-50% more expensive than 304 Stainless Steel.
