UNS number
S31042
Metallurgical class
Austenitic grade: usually predominantly face-centered cubic, hardenable only by cold working
Type
310HCbN (common type number, not a trademark, widely used; not associated with any one product)
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)
Cb 0.20-0.60
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.
