From the standard
Other composition limitsfrom Table 1 and its footnotes
UNS number
S46910
Metallurgical class
Precipitation hardening grade: basically austenitic or martensitic, hardenable by precipitation (age) hardening
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)
Al 0.15-0.50, Ti 0.50-1.20
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.
