From the standard
Other composition limitsfrom Table 1 and its footnotes
UNS number
S30815
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
Other elements (as printed)
Ce 0.03-0.08
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.
