About 316L Stainless Steel
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, is immune from sensitization (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.

Corrosion Resistance
Excellent in a range of atmospheric environments and many corrosive media - generally more resistant than 304. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 60°C.
Heat Resistance
Good oxidation resistance in intermittent service to 870°C and in continuous service to 925°C. Continuous use of 316 in the 425-860°C range is not recommended if 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, both with and without filler metals. Heavy welded sections in Grade 316 require post-weld annealing for maximum corrosion resistance. This is not required for 316L.
Machining
316L stainless steel tends to work harden if machined too quickly. For this reason, low speeds and constant feed rates are recommended. 316L stainless steel is also easier to machine compared to 316 stainless steel due to its lower carbon content.
Hot and Cold Working
316L stainless steel can be hot worked using the most common hot working techniques. Optimal hot working temperatures should be in the range 1150-1260°C. Most common cold working operations such as shearing, drawing, and stamping can be performed on 316L stainless steel.
Hardening and Work Hardening
316L stainless steel does not harden in response to heat treatments. It can be hardened by cold working, which can also result in increased strength.
Applications
- Food preparation equipment particularly in chloride environments
- Pharmaceuticals
- Marine applications
- Architectural applications
- Medical implants, including pins, screws and orthopedic implants like total hip and knee replacements
- Fasteners
