SA387 GR22 CL2 steel plate has the properties of preventing hydrogen embrittlement, hydrogen corrosion, hydrogen peeling, and sulfide corrosion, as well as good low temper embrittlement. It is widely used in the manufacture of fertilizer, petrochemical and thermal power plant equipment. BBNSTEEL has leading production technology, and there are many EN 10025 S550Q high strength steel products in stock. If you need to fix it, it can be 8mm-120mm-650mm thick and wide to 3900mm.

In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like EN 10025 S550Q high strength steel, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.

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. EN 10025 S550Q high strength 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.

Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the EN 10025 S550Q high strength steel steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its EN 10025 S550Q high strength steel steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.
