Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with S420NL carbon steel plate sheet ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.

China's widest bar heating furnace was completed and put into production! During the construction of the heating furnace, the technical experts of Shiheng Special Steel and the technical experts of MCC Southern Thermal Engineering Co., Ltd. demonstrated and designed the bar heating furnace with the widest furnace width, the longest billet and the largest output in China. The heating furnace adopts a number of green and intelligent technologies: the wave-shaped roof design is adopted to strengthen the radiation heat exchange in the furnace and improve the heating efficiency.

Hydrogen (H) is the most harmful element in general steel such as S420NL carbon steel plate sheet. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.
