ASTM A356 Grade 1 (J03502) Cast Carbon Steel

ASTM A356 grade 1 is a carbon steel formulated for casting. Cited properties are appropriate for the heat treated (HT) condition. ASTM A356 Grade 1 is the ASTM designation for this material. J03502 is the UNS number.

The graph bars on the material properties cards below compare ASTM A356 grade 1 to: cast carbon steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
