Properties of 316L
316L stainless steel is easily identified by examining its carbon content - which should be lower than that of 316. Beyond that, here are some 316L properties that also distinguish it from other steel grades.
Physical Properties
316L has a density of 8000 kg/m3 and an elastic modulus of 193 GPa. At a temperature of 100°C, it has thermal connectivity of 16.3 W/m.K and 21.5 W/m.K at 500°C. The 316L also possesses an electrical resistivity of 740 nΩ.m, with a specific heat capacity of 500 J/kg.K.
Chemical Composition
Corrosion Resistance
Grade 316L provides excellent corrosion resistance in a variety of corrosive media and atmospheric environments. It holds up well when subjected to crevice and pitting corrosion in warm chloride situations. Additionally, it proves to stay intact even under stress corrosion cracking tests at above 60 °C. 316L exhibits resistance to water with up to 1000mg/L chloride levels.
316 grade stainless steel is particularly effective in acidic environments - especially when protecting against corrosion caused by sulfuric, hydrochloric, acetic, formic, and tartaric acids, as well as acid sulfates and alkaline chlorides.
Despite being regarded as the standard “marine grade” stainless steel, 316L steel is not resistant to warm seawater - similar to its 316 counterpart. In fact, in several marine environments, 316 exhibits surface corrosion, usually visible as brown staining. This is most prevalent with crevices and rough surface finish.
316L is more corrosion resistant than 316 and 304 stainless steels.
