AH32 Steel Plate | High Strength Shipbuilding Steel Plate

Production Process of AH32 High Strength Shipbuilding Steel Plate

Steelmaking: In the steelmaking process, factories need to precisely control the ratio and chemical composition of raw materials. This ensures the purity of the molten steel and the required alloying element content. This helps AH32 steel plate to obtain good mechanical properties and weldability in subsequent processing.

Continuous casting: Continuous casting is the process of continuous casting of refined molten steel into billets. In this process, workers need to ensure the quality of the billet and avoid defects such as cracks and inclusions. In this way, it can ensure the smooth progress of the subsequent rolling process.

Rolling: Rolling is the process of pressing billets through a rolling mill into steel plates of the desired thickness and width. In the rolling process, it is necessary to strictly control the rolling temperature and rolling speed. This ensures the dimensional accuracy of the steel plate and the uniformity of the internal organizational structure.

Heat treatment: Heat treatment is an important part of the steel plate production process, through heating, insulation and cooling processes, so that the steel plate to obtain the ideal mechanical properties and metallographic structure. For this steel plate, the heat treatment process helps to improve key performance indicators such as yield strength, tensile strength and toughness.

Mechanical Properties of AH32 Steel Plate

1. High strength: The yield strength of AH32 steel plate is as high as 315MPa or more, with high tensile strength and yield ratio. This means that it can withstand large loads and impact forces. In this way, the strict requirements for material strength in the field of Marine and offshore engineering can be met.

2. High toughness: the steel plate still maintains good toughness at low temperature, which can effectively prevent the occurrence of brittle fracture. This is particularly important for ships and offshore structures operating in cold waters.

3. Good weldability: it has good welding performance and can meet the requirements of various welding processes. This helps to achieve good connection and sealing in the manufacture of ships and offshore structures.

4. Excellent corrosion resistance: After special surface treatment (such as painting, galvanized, etc.), this steel plate can resist the erosion of harsh environments such as seawater and chemical substances, and extend the service life. This is of great significance for ships and Marine engineering structures that have been in service for a long time in the Marine environment.
