About the Steel
SS316L is a low-carbon austenitic stainless steel with excellent corrosion resistance, especially in chloride-rich and marine environments.
Molybdenum addition improves pitting and crevice corrosion resistance, while the low carbon content ensures good weldability without post-weld heat treatment.
It retains strength and toughness over a wide temperature range and offers good formability and machinability.
Non-magnetic in the annealed state, it is ideal for chemical, marine, food, and medical applications requiring durability and hygiene.
