From the standard
Other composition limits from Table 1 and its footnotes
UNS number
S32760
Metallurgical class
Austenitic-ferritic (duplex) grade: a mixture of austenitic and ferritic structures, 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)
Cu 0.50-1.00, W 0.50-1.00, %Cr+3.3x%Mo+16x%N>=40
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.
