Pickled steel coils are processed by pickling machines to remove the oxide layer. Because of the deoxidation treatment, certain characteristics of the pickled steel coils are more prominent. First, the surface is smoother and exquisite. For products that require the appearance of the steel plates, pickling steel coil is a good choice. Second, the surface of the pickled steel coil is smooth and not easy to oxidize, and it is convenient and quick to paint. Third, RINA FH36 ocean engineering steel, pickled steel coils have high precision.

Compared with the common pressure vessel, the pressure parts of the boiler not only bear the pressure, but also suffer from the radiation and erosion of the high temperature flue gas. Once the pressure components of the boiler fail in operation, it will cause extremely serious consequences. Therefore, the RINA FH36 ocean engineering steel, steel materials used to manufacture the pressure components of the boiler must have enough high strength, plasticity, toughness, fatigue resistance and corrosion resistance, as well as good high-temperature mechanical properties for high-temperature components.
