Shipbuilding steel plate grade DH36

Shipbuilding steel plate grade DH36 is hull structural steel that processes commendable toughness properties, good tensile strength and excellent corrosion resistance and welding properties. Shipbuilding steel plate grade DH36 is mainly used for platform and shipbuilding.

When rolling shipbuilding steel plate grade DH36, TMCP or Normalized shall be done for heat treatment, and low temperature impacting test have to be done under minus 20 centigree for DH36 steel. In order to improve the thickness-direct steel property for shipbuilding steel plate grade DH36, Z-test is necessary, which includes different classes: Z15, Z25 and Z35.

Shipbuilding steel plate grade DH36 is also conducted tests such as positive material identification test, hardness test, intergranular corrosion test, pitting resistance test, mechanical test, chemical test etc. to assure its quality.
