Q355NH material is a Chinese steel grade to GB/T 4171-2008 atmospheric corrosion resisting structural steel. There are five steel levels under Q355NH: Grade A, B, C, D, and E. Q355NH structural steel sheet is mainly used in vehicles, containers, construction, towers or other structural parts and other structures. It has good resistance to atmospheric corrosion. We supply RA hull construction steel, Q355NH steel plates thickness less than 120mm.
Ordinary carbon structural steel RA hull construction steel has many impurities and low price. The ordinary carbon structural steel is used in places with low performance requirements and low strength, but it has good plasticity, toughness and cold deformation performance. High quality carbon structural steel has less harmful impurities, and its strength, plasticity and toughness are better than those of ordinary carbon structural steel. High quality carbon structural steel is mainly used to manufacture important mechanical parts.
The correct choice of billet type, section shape, size and weight are of great significance to RA hull construction steel steel rolling production. Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality. The consideration of these technical requirements is necessary to ensure the quality of steel. It should also be specifically considered when determining and selecting the blank. The RA hull construction steel rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.
