St37-2 carbon steel plate sheet 500 tons exported to Pakistan

The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of St37-2 carbon steel plate sheet, 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.

It is reported that during the period from the end of 2018 to the first quarter of 2019, some Japanese long process steel mills encountered a series of production line equipment failures, resulting in the overall output decline. Japanese St37-2 carbon steel plate sheet steel mills must give priority to domestic customers, so the export volume in the first half of last year was relatively small. Meanwhile, in the first half of the year, Japan's imports of general St37-2 carbon steel plate sheet steel were about 2.079 million tons, down 16.4% year-on-year; imports of special steel were about 332000 tons, down 14.2% year-on-year.

Q550C steel belongs to low alloy high strength steel. Chemical composition of Q550C steel: C ≤ 0.18, Si ≤ 0.60, Mn ≤ 2.0, P ≤ 0.030, S ≤ 0.030, Nb ≤ 0.11, V ≤ 0.12, Ti ≤ 0.20, Cr ≤ 0.80, Ni ≤ 0.80, Cu ≤ 0.80, N ≤ 0.015, Mo ≤ 0.30, B ≤ 0.004, Al ≤ 0.015. Mechanical properties of Q550C steel: yield strength ≥ 550 MPa, tensile strength 600-780 MPa, elongation after fracture ≥ 16%, impact energy ≥ 55J. St37-2 carbon steel plate sheet, Q550C steel is mainly used for manufacturing various large-scale engineering structural components and construction machinery. Due to its high strength, Q550C steel can meet the requirements of large-scale and lightweight construction machinery.
