The size, shape, weight and allowable deviation of Q390D, Q390D-Z35 steel plate should comply with the provisions of GB/ T709-2016. The maximum thickness of the steel plate is 135mm. When the TM rolled GL-AH 40 hull steel plate, Q390D steel, Q390D-Z35 plate thickness is less than 100 mm, the required performance level in the thickness direction is z25; when the thickness is ≥ 100 mm, the required performance level in the thickness direction is Z35, which shall specifically comply with the provisions of GB/T5313-2010.
Spring steel has good fatigue strength and can be restored to its original state after repeated use, without deformation, because the spring has good ductility and can be changed back to the original state no matter how long it is stretched. TM rolled GL-AH 40 hull steel plate, Spring steel has good elasticity. Spring steel can not only be made into springs, but also be processed into swords, which requires good elasticity. The tensile strength of spring steel is good, it will not break and can be recovered under the condition of tensile limit.
Boiler steel is different from TM rolled GL-AH 40 hull steel plate. Boiler steel is used to make boilers. Boiler steel can be divided into steel for boiler steel pipe, boiler steel plate and boiler steel fasteners. Boiler steel is smelted by open hearth furnace, converter, electric furnace, and some also use the refining process outside the furnace. Boiler steel for steel pipes refers to the steel used for the manufacture of superheaters, reheaters and headers. Their working temperature is higher than other parts, and the environment is also harsher.
The carbon content of TM rolled GL-AH 40 hull steel plate, medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.
