Marine grade FH36 steel impact test temperature and energy

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:

t ≤2.0 in. [50 mm] t>2.0 in. [50 mm]
t≤2.8 in. [70 mm]
t>2.8 in. [70 mm]
t≤4.0 in. [100 mm]

FH36 -76[-60] 25 [34] 17 [24] 30 [41] 20 [27] 37 [50] 25 [34]

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.
