316L and SUS316, both stainless steels, are handy for the food processing and catering industries as they both have excellent corrosion and heat resistance.

316L stainless steel, the "L" in its name stands for low-carbon, meaning it has a low carbon content. This design gives 316L better corrosion resistance and processability. Moreover, it also contains molybdenum, which makes it even more resistant to corrosion and oxidation.

And SUS316 stainless steel, although also corrosion and heat resistant, is not clearly labeled with its carbon content. Therefore, its corrosion resistance may be slightly inferior to 316 L. What's more, during processing, intergranular corrosion is prone to occur because SUS316 may have a higher carbon content.

So, choosing 316L or SUS316 mainly depends on your specific needs and budget. But no matter which material you choose, make sure they meet food safety standards oh!
