ASTM A514 Grade E Steel
ASTM A514 grade E is a type of ASTM A514 steel. Cited properties are appropriate for the quenched and tempered condition. The graph bars on the material properties cards below compare ASTM A514 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.
