From the standard
Other composition limitsfrom Table 1 and its footnotes
UNS number
S43932
Metallurgical class
Ferritic grade: body-centered cubic, little or no tempered martensite, hardenable only slightly 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)
Ti+Cb 0.20+4(C+N) min; 0.75 max, Al 0.15 max
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.
