From the standard
Other composition limits from Table 1 and its footnotes
UNS number
S31603
Metallurgical class
Austenitic grade: usually predominantly face-centered cubic, hardenable only by cold working
Type
316L (designation originally assigned by the American Iron and Steel Institute)
Values
Maximum unless a range or minimum is shown; where two limits are shown for the same element in one grade the more stringent applies
These are the recommended composition limits of the A959 guide, intended for adoption by standards for stainless steel products; they are not a product specification.
