From the standard
Other composition limits from Table 1 and its footnotes
UNS number
S38400
Metallurgical class
Austenitic grade: usually predominantly face-centered cubic, hardenable only by cold working
Type
No type number is printed; the grade is identified by its UNS number only
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.
