ASME SA516GR70 Carbon steel plate for medium and low temperature pressure vessels prime quality hot rolled steel plate

Structural steel for hulls is divided into strength levels according to its minimum yield point: general strength structural steel and high strength structural steel. Structural steel for hulls is divided into general strength and high strength steel. General strength steel is divided into four grades of A, B, D and E according to quality; high strength steel is divided into two strength grades and three quality grades; AH32, DH32, EH32, AH36, DH36, EH36.
General strength structural steel in accordance with China Classification Society specifications is divided into four quality grades: A, B, C, D (i.e. CCSA, CCSB, CCSC, CCSD); high strength structural steel in accordance with China Classification Society specifications is divided into three strength grades and four quality grades.
