Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.
Grade 316L, the low carbon version of 316 and is immune from sensitisation (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). There is commonly no appreciable price difference between 316 and 316L stainless steel.
The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures.
Compared to chromium-nickel austenitic stainless steels, 316L stainless steel offers higher creep, stress to rupture and tensile strength at elevated temperatures.

Application of 316L stainless steel
• Food preparation equipment particularly in chloride environments.
• Marine applications
• Architectural applications
• Medical implants, including pins, screws and orthopaedic implants like total hip and knee replacements
Possible alternative grades to 316 stainless steel.
Why it might be chosen instead of 316?
Better resistance to temperatures of around 600-900°C is needed.
Higher strength than standard 316.
Higher resistance to chlorides than 316L, but with similar resistance to stress corrosion cracking.
Much higher resistance to chlorides at elevated temperatures, with good formability
Much higher resistance to chlorides at elevated temperatures, and higher strength than 316
