Strength and stiffness comparison of ABS EH40 marine steel plate and other marine steel plates

The strength of ABS EH40 marine steel plate mainly includes two indicators of yield strength and tensile strength. According to the ABS specification, the yield strength of ABS EH40 marine steel plate should not be less than 390MPa, and the tensile strength should be 510-660MPa.

Among them, the yield strength refers to the stress value at which the material begins to produce plastic deformation when the stress gradually increases to a certain value during the stretching process of the material, which is called the stress value of the yield point. The tensile strength refers to the maximum tensile stress that the material bears when it breaks during the stretching process of the material.

Therefore, ABS EH40 marine steel plate has high yield strength and tensile strength, and is suitable for manufacturing large-scale marine structures, ocean-going ships and offshore wind power equipment and other fields that require high-strength steel. In addition, ABS EH40 marine steel plate also has good low-temperature toughness and corrosion resistance, and can be used for a long time in harsh marine environments.

ABS EH40 marine steel plate is a high-strength, corrosion-resistant special steel. Compared with other marine steel plates, it has the following characteristics:

1. High strength: ABS EH40 marine steel plate has a yield strength of over 390MPa and a tensile strength of 510-660MPa, which is significantly higher than ordinary marine steel plates.

2. Good toughness: ABS EH40 marine steel plate has good plasticity and toughness, can withstand large impact loads, and also has good low-temperature toughness.

3. Good corrosion resistance: ABS EH40 marine steel plate adopts a certain alloying design to enhance its corrosion resistance, and can be used for a long time in harsh marine environments.

Compared with general marine structural steel, ABS EH40 marine steel plate has higher strength and rigidity, which can meet the high strength requirements of large-scale marine engineering projects and super-large ocean-going ships. But relatively, the cost of ABS EH40 marine steel plate is also higher, and the processing difficulty is also greater. Therefore, it is necessary to comprehensively consider the actual application scenarios and economic costs when selecting marine steel plates.
