DNV Grade DH36,NV D36

Normalised and TMCP rolled DNV Grade DH36,NV D36,DNV DH36 steel plate owned the higher tensile strength within 490-620 Mpa,and the minimum yield point shall be 355 Mpa.Class DH36 indicates the low temperature impacting test shall be done under minus 20 centigree.Xinsteel Industrial exported 50,000 tons higher strength shipbuilding steel materials all over the world especially southeast asia shipyards each year. When delivery shipbuilding steel plates,heat treatment mark would be appear on our each steel plate as steel mark,such as Normalized would be marked as N,TMCP would be marked as TMCP which is short for Thermo-Mechanical Control Process.
