S550QL steel VS a 36 steel plate

The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of S550QL steel, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.

Affected by the weakening of the futures steel market, the market sentiment is cautious. Considering the resource cost, the S550QL steel merchants have strong willingness to stand up price and follow the rise. After the price rise, the S550QL steel merchants' shipment is not smooth, the transaction situation is generally weak, the downstream high level acceptance is weak, and the inventory pressure is not obvious. It is expected that the S550QL steel prices will fall down and adjust in the future.

Q345 steel belongs to low alloy high strength steel, which is mainly used in construction and engineering structure. Q345 steel contains a small amount of alloy elements, and it is widely used in various welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, storage tanks, heavy machinery and equipment, mining machinery, power stations, plant structures, low-temperature pressure vessels, textile machinery parts, etc. Q345 steel has higher yield strength than Q235 steel. Of course, the price of S550QL steel, Q345 steel is higher than that of Q235.
