sa573 gr.70 carbon-manganese-silicon steel customized

Cleveland cliffs announced on March 13 that it had completed the acquisition of AK sa573 gr.70 carbon-manganese-silicon steel steel, foreign media reported In the transaction of holding), shareholders of Cleveland cliffs and AK steel respectively voted on the US billion acquisition agreement at their respective shareholders' meeting to complete the resolutions required for the announcement of acquisition of AK steel sa573 gr.70 carbon-manganese-silicon steel at the beginning of the year. The acquisition is Cleveland cliffs' first foray into steel manufacturing.

sa573 gr.70 carbon-manganese-silicon steel, Wear-resistant steel plates are mainly made of some alloying elements, such as manganese, silicon, chromium, vanadium, aluminum, titanium, boron, rare earths elements and so on. Generally, manganese and silicon are added first, because this can further strengthen the deoxidation effect, and because their prices are relatively low, adding them early can ensure the yield of the elements added later.

Chemical composition of Q390C steel plate: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.7, P ≤ 0.030, S ≤ 0.030, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.50, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.10, Al ≤ 0.015. The mechanical properties of Q390C steel plate are: yield strength ≥ 390 MPa, tensile strength 470-620 MPa, elongation after fracture ≥ 18%, impact energy 34J. sa573 gr.70 carbon-manganese-silicon steel, Q390C steel plate is used for bridges, vehicles, ships, workshops and other large structural parts, high and medium pressure Petrochemical vessels, boiler tubes, pipes, superheaters, pressure vessels, heavy machinery, etc. application.

The sa573 gr.70 carbon-manganese-silicon steel company has established the corporate values of being proud of innovation and winning, and successfully realized the management of corporate culture. In BBN, leaders are not controllers and supervisors, but earnest sa573 gr.70 carbon-manganese-silicon steel teachers, coaches and enthusiastic friends, so that employees can have more democracy, more autonomy, independence and creativity, and the belief of winning.
