For example, the “L” stands for “low” in 316l stainless steel and signifies that this alloy has a very low carbon content. The 316l variant is also more resistant to weld decay in comparison with 316 and it can withstand higher temperatures. That's why 316l is used often in marine and construction projects.316L is the superior choice for high corrosion and high temperature applications. Since 316L contains less carbon than 316, it has better intergranular corrosion resistance, meaning its welds won't decay, unlike with 316 stainless steel
