ASTM A131 EH40 steel plate is a kind of high strength steel for ship structures, it has good mechanical and technological properties, and its yield strength is more than 315 Mpa. In order to prevent fracture accident and brittle fracture at low temperature,
ASTM A131 EH40 steel plate has a good elongation. Its toughness at -40℃ is not less than 50% of normal temperature. ASTM A131 EH40 steel plate can be cold-formed and can be used as engineering structure in cold regions.
