Eh32 and Eh36
Strength Comparison: The yield strength of Eh32 is not less than 315 MPa, and that of Eh36 is not less than 355 MPa. Eh36 has higher strength and can be used in parts of the ship's structure that require higher bearing capacity, such as the oil tank bulkheads of large oil tankers; Eh32 has slightly lower strength but can also meet the general requirements of the ship's structure, such as the ship plates of some small ships.
Corrosion Resistance: Both of these steels take into account the corrosiveness of the marine environment. They improve their corrosion resistance by adding alloy elements such as chromium (Cr) and nickel (Ni) (although the contents are relatively low), and can effectively resist the electrochemical corrosion of seawater, prolonging the service life of the ship.
Machining Performance: They have good performance in both cold working and hot working. In shipbuilding, operations such as cutting, bending, and stamping need to be performed on steel plates. Eh32 and Eh36 can well adapt to these machining processes, ensuring the shape accuracy and mechanical properties after machining.

 

Fh36
Special Properties: Besides having a high yield strength (not less than 355 MPa), Fh36 may also have outstanding performance in aspects such as fatigue resistance. Under the long-term action of waves, the ship's structure will bear alternating stresses, and the fatigue resistance of Fh36 can reduce the possibility of cracks in the structure due to fatigue.
Quality Control: The quality control requirements in the production process are strict. From the selection of raw materials to the rolling process and then to the inspection of finished products, it is necessary to ensure that its performance complies with the standards of the classification society. For example, in terms of the thickness tolerance control of steel plates, precise requirements need to be met to ensure the assembly accuracy of the ship's structure.

 

Introduction to Hot Rolling Process

 

Hot Rolling Process
Hot rolling uses slab (mainly continuous casting slab) as raw material. After heating, it is made into strip steel by the rough rolling mill group and the finish rolling mill group. The heating temperature is generally around 1100 - 1250°C. This temperature range can make the steel have good plasticity, facilitating rolling. In the rough rolling stage, the slab is initially rolled into an intermediate billet of a certain shape and size through a large reduction. Then, in the finish rolling stage, it is further rolled into the required thickness of the steel plate, and the performance of the steel plate can be improved by controlling parameters such as rolling speed.

 

Influence of Hot Rolling on Steel Properties
Hot rolling can refine the grain structure of the steel, improving its strength and toughness. By reasonably adjusting hot rolling process parameters such as final rolling temperature and cooling speed, the steel can obtain an ideal microstructure. For example, appropriately reducing the final rolling temperature can refine the grains, thereby improving the strength and toughness of the steel, making it more suitable for shipbuilding requirements.

Quality Inspection and Classification Society Certification

 

Quality Inspection Items
Mechanical Property Testing: It includes tensile tests, impact tests, etc. The tensile test is used to determine the yield strength, tensile strength, and elongation of the steel; the impact test is used to detect the toughness of the steel at different temperatures to ensure its safe use under various environmental conditions.
Chemical Composition Analysis: The content of various elements in the steel is detected by methods such as spectral analysis to ensure that its chemical composition complies with the standard requirements of grades such as Ah36, Dh36.
Dimensional Accuracy Inspection: The thickness, length, width, etc. of the steel plate are inspected to see if they meet the specified tolerance ranges, ensuring the assembly accuracy in the shipbuilding process.
