 a. ST - solution treated; NT - normalized and tempered; A - annealed; See ASTM A 743nTable 1 and ASTM A 890 Table 1 for detailed
 heat treatment requirements.
 b. For low ferrite or non-magnetic castings of this grade, the following values apply: tensile strength 65 ksi (450 MPa) min., yield strength 28
 ksi (195 MPa) min.
 c. Hardness values are supplementary requirements in ASTM A 743-91 S14 and are maximum values, unless otherwise specified.
 d. The hardness requirement for this grade in the annealed condition is 269 HB max.
 e. Supplementary requirement S32 of ASTM A 890-91a.
 All values are minimums, unless otherwise specified.
