What is the difference between 316L and 316 stainless steel

What is the difference between 316L and 316 stainless steel

316,18Cr-12Ni-2.5Mo
Due to the addition of Mo, it has excellent corrosion resistance, atmospheric corrosion resistance and high temperature strength, and can be used under harsh conditions; it has excellent work hardening (non-magnetic)
Seawater equipment, chemical, dye, paper, oxalic acid, fertilizer and other production equipment; photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts
316L, 18cr-12ni-2.5mo low carbon
As 316 steel, low C series has the same characteristics as 316 steel, and has excellent grain boundary corrosion resistance
Among the applications of 316 steel, products with special requirements for resistance to grain boundary corrosion
