316 Stainless Steel | Stainless Steel Supply

316 stainless steel is a type of austenitic stainless steel that contains 16-18% chromium, 10-14% nickel, 2-3% molybdenum, and other elements such as manganese, silicon, and carbon. It is a highly corrosion-resistant alloy that is widely used in various applications where resistance to corrosion and high temperature is required.

The addition of molybdenum to 316 stainless steel makes it more resistant to pitting and crevice corrosion in chloride environments than other stainless steel grades. It also enhances the alloy’s strength and toughness, making it suitable for applications such as chemical processing, marine environments, and medical devices.

316 stainless steel is also known as marine grade stainless steel due to its excellent corrosion resistance in saltwater and other corrosive environments. It is often used in the construction of boats, yachts, and other marine equipment.

In addition to its corrosion resistance, 316 stainless steel has good weldability and formability, making it easy to work with. It is also resistant to high temperatures and is often used in applications where exposure to extreme heat is a concern.
