ABOUT STAINLESS STEEL 316L
Stainless Steel 316L is a molybdenum-bearing austenitic stainless steel with superior corrosion resistance compared to 304L, especially against chloride environments. It is used in marine and coastal launch facility infrastructure and propellant handling systems. The low carbon variant resists sensitization during welding.
