China Prime 15MM EH32 Shipbuilding Steel Plate

 

"China Prime 15MM EH32 Shipbuilding Steel Plate" refers to high-quality 15-millimeter-thick EH32 shipbuilding steel plate from China. Here is a detailed introduction to it:

 

Chemical Composition:

 

Carbon (C): The content is usually ≤0.18%. Controlling the carbon content helps ensure the welding performance and toughness of the steel plate and avoid making the plate too hard and brittle.

Silicon (Si): The content is between 0.10% and 0.50%. An appropriate amount of silicon can improve the strength and oxidation resistance of the steel plate.

Manganese (Mn): It is between 0.90% and 1.60%. Manganese plays an important role in improving the strength and toughness of the steel plate.

Phosphorus (P): ≤0.04%. Phosphorus is a harmful element. Excessive content will reduce the toughness and weldability of the steel plate, so it needs to be strictly controlled.

Sulfur (S): ≤0.04%. Sulfur can cause defects such as hot cracks in the steel plate. Low sulfur content can improve the quality of the steel plate.

Other elements: It may also contain a small amount of aluminum (Al) ≥0.015%, as well as trace elements such as vanadium (V) and niobium (Nb). These elements can improve the performance of the steel plate.

Mechanical Properties:

 

Yield strength: ≥315 MPa. Yield strength refers to the stress value at which the steel plate begins to undergo plastic deformation when subjected to force. A higher yield strength can ensure that the steel plate is not easily deformed during use.

Tensile strength: 440 - 570 MPa. Tensile strength reflects the maximum tensile force that the steel plate can withstand. The tensile strength within this range enables the steel plate to have sufficient strength to bear various stresses on the ship structure.

Elongation: ≥22%. Elongation reflects the plastic deformation ability of the steel plate before fracture. A higher elongation means that the steel plate has better toughness and processability.

Impact toughness: Under specific low-temperature conditions, such as at 0°C, there are certain requirements for impact work (absorbed energy). This indicates that the steel plate still has good impact resistance at low temperatures and can adapt to the use of ships in different sea areas and climatic conditions.

 

Specification and Size:

 

Thickness: 15 millimeters is the specific thickness of this steel plate. The thickness of shipbuilding steel plates is usually selected according to different parts and stress requirements of the ship structure.

Width: Generally, it is between 1000 and 3000 millimeters. The common width is between 1000 and 2200 millimeters and can be customized according to actual needs.

Length: Usually it is between 1000 and 12000 millimeters and can also be cut and processed according to customer requirements.
