About 316L Stainless Steel
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 offering higher resistance to pitting and crevice corrosion in chloride environments.
Grade 316L is the low carbon version of 316, making it immune from sensitization (grain boundary carbide precipitation). This makes it extensively used in heavy gauge welded components (over about 6mm). There is typically no appreciable price difference between 316 and 316L stainless steel.
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. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above approximately 60°C. Considered resistant to potable water with up to about 1000 mg/L chlorides at ambient temperatures, reducing to about 500 mg/L at 60°C.
316 is typically regarded as the standard "marine grade stainless steel," though it is not resistant to warm seawater. In many marine environments, 316 may exhibit surface corrosion, usually visible as brown staining, particularly in crevices and areas with rough surface finish.
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. Grade 316L is more resistant to carbide precipitation and can be used in this temperature range. Grade 316H has higher strength at elevated temperatures and is sometimes used for structural and pressure-containing applications above approximately 500°C.
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. 316L stainless steel is not generally weldable using oxyacetylene welding methods.
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 common techniques. Optimal hot working temperatures should be in the range 1150-1260°C, and certainly should not be less than 930°C. Post-work annealing should be carried out to induce maximum corrosion resistance.
Most common cold working operations such as shearing, drawing, and stamping can be performed on 316L stainless steel. Post-work annealing should be carried out to remove internal stresses.
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.
