Composition and Characteristics
The superior performance of 316L stainless steel is due to its carefully balanced chemical composition, which typically includes:
Chromium (Cr):16-18%
Nickel (Ni):10-14%
Molybdenum (Mo):2-3%
Carbon (C):0.03% max
Manganese (Mn):2% max
Silicon (Si):1% max
Phosphorus (P):0.045% max
Sulfur (S):0.03% max
The addition of molybdenum significantly enhances the alloy’s resistance to pitting and crevice corrosion, particularly in chloride-rich environments such as seawater. The low carbon content helps prevent carbide precipitation during welding, ensuring that the material maintains its corrosion resistance and strength without requiring post-weld annealing.
Key Properties
316L stainless steel bar is prized for several key properties that make it an excellent choice for a wide range of applications:
Superior Corrosion Resistance:316L stainless steel offers exceptional resistance to a variety of corrosive environments, including those with exposure to chlorides, acids, and alkalis. This makes it ideal for use in marine, chemical, and pharmaceutical industries.
