ASTM A203 Grade E Nickel Steel

ASTM A203 grade E is a type of ASTM A203 steel. Cited properties are appropriate for the normalized condition. The graph bars on the material properties cards below compare ASTM A203 grade E to: wrought alloy steels in the same category (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.
