316L Stainless Steel Properties
Grade 316 is the standard molybdenum-bearing austenitic stainless steel, second in importance to 304. The molybdenum content provides 316 with superior corrosion resistance compared to Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.
Grade 316L is the low carbon version of 316, immune from sensitization (grain boundary carbide precipitation). This makes it extensively used in heavy gauge welded components (over about 6mm). The austenitic structure provides excellent toughness, even at cryogenic temperatures.

Performance Characteristics
Corrosion Resistance
Excellent performance in various atmospheric environments and corrosive media, generally more resistant than 304. Resistant to pitting and crevice corrosion in warm chloride environments. Considered resistant to potable water with up to 1000 mg/L chlorides at ambient temperatures.
Heat Resistance
Good oxidation resistance in intermittent service to 870°C and continuous service to 925°C. Grade 316L is more resistant to carbide precipitation and can be used in temperature ranges where subsequent aqueous corrosion resistance is important.
Heat Treatment
Solution Treatment (Annealing) - Heat to 1010-1120°C and cool rapidly. These grades cannot be hardened by thermal treatment.
Welding
Excellent weldability by all standard fusion and resistance methods. Heavy welded sections in Grade 316 require post-weld annealing for maximum corrosion resistance, which is not required for 316L.
Machining
316L stainless steel tends to work harden if machined too quickly. Low speeds and constant feed rates are recommended. Easier to machine compared to 316 stainless steel due to lower carbon content.
Hot and Cold Working
Optimal hot working temperatures: 1150-1260°C. Most common cold working operations can be performed. Post-work annealing recommended for maximum corrosion resistance and stress relief.
Hardening
Does not harden in response to heat treatments. Can be hardened by cold working, resulting in increased strength.
Applications
- Food preparation equipment in chloride environments
- Pharmaceutical manufacturing
- Marine applications
- Architectural components
- Medical implants and orthopedic devices
- Industrial fasteners
- Chemical processing equipment
