Stainless steels which – beside the necessary percentage of Chromium – contain a good amount of Nickel and possibly of Molybdenum.

END USES
As with AISI 316 steel, AISI 316L can also be used for end uses where good formation must be coupled with excellent resistance to corrosion. The reduced percentage of carbon (under 0.03%) is particularly useful to exceed problems of intercrystalline corrosion, which typically appears in welding processes, where temperatures can be reached of around 450-850 degrees.
Dual certification: Since the steel belongs to the AISI 316L range, a sub-category of AISI 316, it can be used in all cases where AISI 316 is used, in particular in products where welding plays an essential role, i.e. architectural finishes for outdoors, tanks, industrial autoclaves, etc.
