The corrosion resistance between 316 Stainless Steel and 304 Stainless Steel

Contrary to its name, stainless steel is respect for their anti-corrosion properties than its resistance to staining. It is an alloy composed mainly of iron-but when combined with other elements, it can be desirable properties for a range of applications to achieve. Chromium is the defining ingredient that makes stainless steel with it, making up a minimum of 10.5 percent of the total composition. Among the other ingredients commonly nickel alloys, titanium, aluminum, copper, nitrogen, phosphorus and selenium.

Can be different quantities of chromium, as well as other materials, can be used to varying degrees to achieve corrosion resistance. The two most common stainless steel grades 304 and 316. erosion is a natural phenomenon. Pure Elements such as iron, basically react with surrounding environments. In fact, very little can get natural elements in their pure form of gold, silver, copper and platinum become part of the small samples. The process is rust iron combined with oxygen molecules present in the water. The result is a flaky red oxide material that deteriorates more easily revealing more erosion. Iron and standard carbon steels are very susceptible to this type of corrosion.

Stainless steel, however, has the innate ability to form a protective surface to prevent corrosion. How does this happen? The chromium found in all stainless steels react rapidly with oxygen environments, much as the same iron. The difference, however, that only a very fine layer of chromium oxidize (often just a few molecules in thickness). This is extremely thin barrier very durable and non-reactive. It adheres to surfaces of stainless steel and will not transfer or further react with other materials. It is the self-renewal in that it will replenish if damaged or removed also. Once oxidized, or passivized, stainless steel rusts usually at a very low rate of less than 0.002 inches per year. Both 304 and 316 stainless steels (along with other grade 300-series) using nickel to maintain an austenitic composition at lower temperatures. Austenitic steels versatile balance of strength, workability and corrosion resistance, making them ideal for architectural applications and outdoor landscape. On the advantages of stainless steel with long service life to keep attractive, clean finish with low maintenance cost. It also maintains a high value if and when needed equipment and parts to be decommissioned.
