The deoxidation ability of Al is much stronger than that of Si and Mn when aluminum element (Al element) is added into steel as deoxidizer or alloying element. The main role of aluminum in LR EH40 wash bulkhead steel etc. steel is to refine grain size and fix nitrogen in steel, so as to significantly improve the impact toughness of steel and reduce the tendency of cold brittleness and aging. Al element can also improve the corrosion resistance of steel, especially when used with molybdenum, copper, silicon, chromium and other elements. The wear resistance of chromium molybdenum steel and chromium steel can be increased by containing Al element.

In terms of ship steel, according to industry experts, steel is mainly used in the construction of ship hulls, cargo holds, piping systems (including pumps and valves) and part of ship decoration. In addition to being used to build conventional ships, steel also plays an important role in the construction of various special ships such as LNG (liquefied natural gas) ships, large oil tankers, large container ships, and chemical tankers.
