  1. Type 316 contains slightly more nickel than 304 and 2-3% molybdenum giving it better resistance to corrosion than 304, especially in chloride environments that tend to cause pitting. It offers superior performance when exposed to sea water and resists corrosion in sulfuric acid compounds
  2. 316 stainless steel boasts a higher strength and durability than 304 stainless steel. It also has a higher level of corrosion resistance, including when exposed to salt water. It performs well against pitting and is also resistant to caustic chemicals. As mentioned above, however, 316 stainless steel is less malleable than 304 stainless steel
  3. Marine Grade Stainless Steel 316 is similar to Stainless Steel 304 in the composition of chromium and nickel, however it contains about 2 to 3 % of molybdenum in addition which greatly increases corrosion resistance of the steel
  4. Two of the most common grades of austenitic stainless steel are 304 (1.4301) and 316 (1.4401). In appearance the 2 are indistinguishable and the few tests to differentiate between them include either hazardous chemicals (in the case of a molybdenum drop test) or expensive equipment (such as positive material identification)
  5. While stainless steel grades 304, 316 and duplex steels can all be used in marine applications, they do provide varying degrees of corrosion resistance and durability. The key to their successful application is, therefore, being aware of the strengths and limitations of each grade and how they can be used to their optimum potential

A major difference between 304 and 316 stainless steel is the chemical composition, with 316 containing a significant amount of molybdenum; typically 2 to 3 percent by weight vs only trace amounts found in 304. The higher molybdenum content results in grade 316 possessing increased corrosion resistance However, 304 stainless steel does have one weakness, and that is it does not perform well in chloride environments, in particular, seawater. It is susceptible to corrosion in these cases. If marine corrosion is a major concern, a better choice would be 316 stainless steel, which has 2 percent molybdenum added to it
