END USES
As with the other austenitic steel types, AISI 316 can also be used for end uses where good formation must be coupled with excellent resistance to corrosion. Compared to the more traditional AISI 304, the additional small percentage of Molybdenum makes the steel in this series particularly resistant to corrosion (in particular pitting) even in particularly reducing environments, highly saline environments, etc.
These peculiar characteristics make it particularly suitable for the paper industry and tanks for the chemical industry.
