Marine Grade 316 StAINLESS Steel

Stainless steel is a metal alloy that’s widely used in a variety of applications. It is durable, versatile and easy to clean, making it a popular choice for kitchen appliances, car parts, wheel covers and more.

The key to stainless steel’s longevity is chromium, an element that reacts with oxygen when exposed to the air to form a thin layer of rust-resistant oxide on its surface. The oxide protects the metal from further oxidisation and corrosion, and it also prevents the formation of harmful substances such as nitrous oxide, hydrogen sulphide and carbon monoxide, which can attack and weaken the structural integrity of the steel.

Marine grade 316 stainlees steel contains the same chromium content as other grades of stainless steel, but it also has up to 3% molybdenum—a hard and tough metallic element that increases its resistance to degradation from salt water. This gives it superior corrosion resistance, particularly to pitting and crevice corrosion. It also holds up better against the acidic environments found in marine conditions, including chlorides, sulphuric and sulfuric acids.

As a result of these properties, it’s often chosen for components that will be submerged in water or harsh chemicals. It’s also used for plumbing fixtures like shower drains, as it can stand up to the repeated exposure to salt, harsh cleaning products and other corrosives that these installations are likely to experience.


Are There Specific Standards Or Certifications For Marine Grade 316 StAINLESS Steel?

There are no governmental standards for marine grade 316 stainless steel. However, there are several voluntary certifications that can be obtained, including NSF, UL and ASME. These certificates can provide proof that the product has been independently tested and meets certain criteria, such as corrosion resistance, mechanical properties and quality control procedures.

Besides being able to stand up to salt, harsh chemicals and other environmental factors, marine grade 316 stainless steel is also known for its beauty and durability. It has a lustre that’s easy to clean and maintain, and it can enhance the aesthetics of many architectural styles and settings.

316 stainless steel is a common choice for commercial food processing equipment because of its high strength, good weldability and non-reactivity with foods. It’s also commonly used in chemical storage and transport equipment and for the cladding of nuclear fuel and oil refining equipment. It can be used in medical applications, too, as it resists iodides, bromides, chlorides and sulfuric acids.

At The Lighting Outlet, we stock a wide selection of 316 stainless steel plate for use in fabrication projects where moisture will be present. Our 316/316L plates are dual certified as both straight and marine grade and have a carbon level that is held to 0.08% maximum, which minimizes carbide precipitation during welding. Contact us today to learn more about our stock sizes and to place an order. Our experienced staff is happy to answer any questions you may have. We can help you find the best solution for your needs and ensure that your project is a success.
