Strength and Toughness Optimization: By controlling the addition amounts of these micro - alloying elements, the steel plates can obtain higher strength without increasing too much carbon content, while maintaining good toughness and welding performance. For example, while ensuring that the strength of the marine - use steel plates meets the requirements, good toughness enables them to better withstand various complex stresses during the voyage of the ship, such as wave impacts and collisions during cargo loading and unloading. Moreover, this optimized performance can also meet the processing - technology requirements during ship - building, such as cutting, bending, and welding.

 

Copper (Cu) Element (May be Present)

 

Corrosion - Resistance Enhancement: Some AH36 marine steel plates may contain a small amount of copper element. Copper can improve the corrosion - resistance of the steel. Especially in some marine environments, seawater contains corrosive media such as salt. The copper element can form a protective film on the surface of the steel, slowing down the corrosion rate of seawater on the steel plates. This is very important for the long - term use of ships, because the ship's hull and other structural components are soaked in seawater for a long time. Good corrosion - resistance can extend the service life of the steel plates, reducing the frequency of maintenance and replacement.

Strength - Assistance Enhancement: Copper can also improve the strength of the steel to a certain extent. However, too much copper may lead to hot - working defects in the steel, so its content is usually reasonably limited. An appropriate amount of copper element, in cooperation with other elements, can optimize the comprehensive performance of AH36 steel plates, making them better adapt to the requirements of the ship structure.
