CCSDH40 steel plate implementation standard: the implementation of GB/T712-2011 standard.

GB/T712-2011 Structural steel standard for ships and offshore engineering The grades specified are: A, B, D, E, AH32, DH32, EH32, FH32, AH36, DH36, EH36, FH36, AH40, DH40, EH40, FH40, AH420, DH420, EH420, FH420, AH460, DH460, EH460, FH460，AH500，DH500，EH500，FH500，AH550，DH550，EH550，FH550，AH620，DH620，EH620，FH620，AH690，DH690，EH690，FH690。

CCSDH40 heat treatment: normalizing, annealing, controlled rolling, tempering, quenching, quenching and tempering, CCSDH40 etc.

Width: 1600-4020mm; Length: 6000-17500mm.

CCSDH40 steel plate flaw detection requirements: one probe, two probe, three probe.

CCSDH40 cutting process: the steel plate factory inspection of the performance indicators meet the requirements in accordance with the cutting process, can be cut processing and drawing blanking, the general thickness of the steel plate is not more than 20mm, the preferred choice of CNC plasma cutting or CNC laser cutting, if the thickness of the steel plate is greater than 30mm, usually will choose CNC flame cutting, you can control the cutting accuracy and time.

CCSDH40 used to manufacture the hull structure of ships for ocean, coastal and inland navigation, and is often used in shipbuilding, offshore construction platforms, port machinery, marine parts manufacturing, marine pipeline deck machinery, etc.
