ASTM A131 grade E material properties
ASTM A131 specification covers structural steel plates, shapes, and bars intended primarily for use in ship construction. Material under ASTM A131 specification is available in the following categories: Ordinary strength-grades A, B, D, and E with a specified minimum yield point of 34 ksi [235 MPa], and higher strength-grades AH, DH, EH, and FH with a specified minimum yield point of 46 ksi [315 MPa], 51 ksi [350 MPa], or 57 ksi [390 MPa]. ASTM A131 grade E material is ordinary strength steel, with maximum thickness of A131 grade E plates is 4 in. [100 mm].
