Marine grade FH36 steel is produced in accordance with the requirements of the classication society for the construction of ship hull structures. Marine grade FH36 steel is able to resist corrosive effects that are common in a water environment. FH36 steel impact test needs to be done under -60℃.
Marine grade FH36 steel impact test temperature and energy:

Marine grade FH36 steel is added with special alloying elements, so as to defend agaist corrosion. FH36 steel not only has good low temperature resistance and welding adaptability, but also has high extension function, which enables it to absorb the collision energy, so as to improve the anti-collision ability of the ships.
GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
