Hot Rolled Steel Plate SA572 Gr 50 carbon steel plate sheet Carbon Steel Sheet

SA283 Gr C plate chemical composition: C≤0.24, Si≤0.40, Mn≤0.90, P≤0.035, S≤0.040, Cu≥0.20.SA283 Gr C plate strength properties: yield strength 380-515 Mpa, tensile strength ≥205 Mpa.Application scope of SA283 Gr C plate, SA572 Gr 50 carbon steel plate sheet: SA283 Gr C steel plate is suitable for riveting, bolt linking and welding structures of bridges and buildings. It is a general-purpose carbon steel with structural steel quality.

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.

The weldability of SA572 Gr 50 carbon steel plate sheet is good. It means that under certain process and construction conditions, SA572 Gr 50 carbon steel plate sheet can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.

How to prevent SA572 Gr 50 carbon steel plate sheet, steel plate cutting cracks? 1. Preheat the steel plate before cutting, and the preheating temperature depends on the quality grade and thickness of the steel plate. However, it needs to be heated evenly. 2. The cutting speed is reduced appropriately, but its reliability is not as good as preheating. It is suggested to preheat the cutting belt with flame gun cavitation several times before cutting, and the preheating temperature should reach about 180℃.
