1. Material and performance
Strength:
EH36 and DH36 both have high yield strength and tensile strength, which can meet the requirements of ship structure for material strength. Specifically, the yield strength of both is not less than 355MPa, and the tensile strength is between 490-630MPa.
Impact toughness:
EH36: has good impact toughness and low-temperature toughness, and can maintain good performance at a temperature of -40℃.
DH36: also has excellent impact toughness, but the temperature of its impact test is -20℃, which is slightly higher than that of EH36 in a low-temperature environment.
Welding performance:
EH36 and DH36 both have good welding performance, and are easy to carry out various welding processes, such as manual arc welding, submerged arc welding, gas shielded welding, etc., which can ensure the quality and strength of the welded joints.
Processing performance:
Both have good processing performance, and are easy to carry out cutting, bending, forming and other processing processes, which facilitates processing and installation during the manufacturing process.
Corrosion resistance:
Both EH36 and DH36 have undergone special surface treatment and have good corrosion resistance. They can operate for a long time in the marine environment without being affected by corrosion.
2. Application fields
EH36:
It is widely used in shipbuilding, such as the hull structure of various types of ships such as cargo ships, oil tankers, and container ships. Its high strength and good welding performance make the ship structure more stable and able to withstand the test of complex marine environments.
In the field of marine engineering, EH36 is also used in the construction of facilities such as offshore platforms and submarine pipelines. Its excellent corrosion resistance and low-temperature toughness enable these facilities to operate stably and for a long time in harsh marine environments.
In addition, EH36 also plays an important role in bridge construction, especially long-span bridges and highway bridges.
DH36:
It is also widely used in the fields of marine engineering and shipbuilding, especially in situations where higher strength and good welding performance are required.
Its application field is similar to that of EH36, but due to the different impact test temperatures, DH36 is slightly inferior to EH36 in applicable ambient temperature.
3. Summary
Both EH36 and DH36 ship plates have excellent performance in terms of materials and performance, with high strength and good welding, processing and corrosion resistance. The main difference between the two is the different temperatures of the impact test, which determines their applicability in different low temperature environments. When choosing, it should be considered according to the specific application environment and needs.
