Which Stainless Steel Should Be Specified for Exterior Performance of Stainless Steel in Marine Environments
stainless steel is aesthetically unacceptable even if there is no struc tural deterioration. Identifying a stainless steel that meets this aesthetic standard and is cost effective requires evaluation of the site environment, weather, finish, design and probable maintenance schedule. The Whats the Difference? - United Performance Metalsapplications involving fresh water environments. It is generally considered one of the most widely-used austenitic stainless steels. 316, with its addition of molybdenum, is considerably more resistant to corrosive environments than 304. 316 is more suitable for sea water environments and marine applications. Because of its greaterWhat is 316 Grade Stainless Steel? - Definition from Performance of Stainless Steel in Marine Environments Mar 21, 2017316 grade stainless steel is an austenitic form of stainless steel known for its 2-3% molybdenum content. The added molybdenum makes the metal more resistant to pitting and corrosion, as well as improving resistance when exposed to elevated temperatures. This grade of stainless steel is particularly effective when used in acidic environments.

The durability prevents having to replace equipment or excessive maintenance. Strong as Steel. In terms of strength, steel that has been galvanized and stainless steel are both strong options. However, carbon steel is generally 40 percent stronger. The use of additional components of stainless steel means that it takes more material to achieve the same strength as standard carbon steel.Stainless Steel Corrosion Data Just MfgMarine environments are also high in chlorides and are notoriously aggressive to metals, but stainless steels are preferred for construction in many coastal applications. A thin rust film may develop on the surface of those stainless steel types, but in most instances this is more a visual impairment than a functional failure from corrosion.
