Introduction of CCS DH32 shipbuilding steel plate:
CCS DH32 shipbuilding steel plate is plate with thickness less than 150 mm for the manufacture of ocean-going, coastal and inland navigation vessels, fishing vessels and marine engineering structures. The CCS DH32 shipbuilding steel plate with Z direction requirement is suffixed with Z25 and Z35. CCS DH32 shipbuilding steel plate is for the purpose of high strength structural steel for ships and marine engineering.
Size, shape, weight and allowable tolerance of CCS DH32 shipbuilding steel plate:
The size, shape, weight and allowable tolerance of the CCS DH32 shipbuilding steel plate shall comply with the requirements of GB/T709, and the thickness tolerance under shall be -0.3mm.
Delivery status of CCS DH32 shipbuilding steel plate:
CCS DH32 shipbuilding steel plate is usually delivered in hot rolling, controlled rolling, normalizing and thermomechanical rolling state.
CCS DH32 shipbuilding steel plates shall be delivered by shearing or flame cutting

Nondestructive testing of CCS DH32 shipbuilding steel plate:
Z-direction CCS DH32 shipbuilding steel plate shall be inspected by ultrasonic wave, and the inspection level shall be specified in the contract.
According to the requirement of the user, other CCS DH32 shipbuilding steel plates can also be tested nondestructively by agreement between the supplier and the user.
GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
Bulb flat steel for shipbuilding
The bulb flat steel is a kind of medium section material which is mainly used in the field of shipbuilding and bridge building, and the shipbuilding bulb flat steel is an auxiliary medium section material for shipbuilding.
