What's the difference between 316 and 316L Stainless Steel ?
316 and 316L stainless steel alloys are both marine-grade steels, but they do possess some key differences.
316L has a lower proportion of carbon in its composition.
To qualify as 316L stainless steel, the amount of carbon cannot exceed 0.03%. This decreases the risk of carbon precipitation, making it a better option for welding to ensure maximum corrosion resistance.
316 stainless steel has a mid-range level of carbon and contains between 2% and 3% molybdenum, which increases resistance to corrosion, acidic elements, and high temperatures. Both materials have excellent malleability, meaning they perform well in bending, stretching, deep drawing, and spinning.
