Excellent in a normal range of corrosive media, more resistant than 304. Subject to internal material pitting and crevice corrosion in warm acidic environments and to stress corrosion cracking above 60ºC.
Considered resistant to potable water with about 1,000 mg/L chlorides at ambient temperatures, reducing about to 500 mg/L at 60ºC.
316 has good oxidation resistance in intermittent service to 870ºC and in continuous service to 925ºC. However, it will have reduced aqueous corrosion resistance in the temperature range of 425-860ºC. Grade 316L is more resistant to carbide precipitation since it has lower carbon (C) percentages.Excellent weldability by all standard methods such as; electrode, gas, rod welding, etc..
Welding of 316 is pre-qualified with Grade 316 and 316L with Grade 316L rods or electrodes. Heavy welded sections in Grade 316 require post-weld annealing, but this is not required in lighter welded sections. Grade 316L does not require that even for heavy welded sections (e.g. for 6mm and over). Grade 316Ti should be used as an alternative to 316 for heavy section welding. APPLICATIONS:
Food preparation equipment particularly in acidic environments.
Laboratory benches & equipment, medical equipment
Coastal architectural paneling, railings & trim
Boat and ship fittings
Chemical containers for transport
Bolts, bolt pins, screws, etc.
