The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of API 5L PSL1 Gr.B specification, 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.
The demand for iron ore from steel production has weakened. As China’s domestic market enters the off-season for consumption, the demand for iron ore from steel production will weaken to a certain extent. Affected by the fall and winter environmental protection production restrictions and the expected release of national scrap steel standards at the end of the year, the market outlook is expected to decline and prices will not rise Shows a volatile downward trend. Steel production declined slightly, and the demand for iron ore weakened.
Fake and inferior steel plates are easy to scratch because of the simple equipment of the manufacturers of fake and inferior materials, which are easy to produce burrs and scratch the surface of the steel plate. Deep scratches reduce the strength of the API 5L PSL1 Gr.B specification, steel plate. The surface of the fake and inferior material is prone to cracks, because its billet is adobe, which has many pores. The adobe is subjected to thermal stress during the cooling process, and cracks are generated, and there will be cracks after rolling.
