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. S460M material, 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.
In the first quarter, S460M material, crude steel output in Asia amounted to 315.15 million mt, falling by 0.3 percent, with 234.45 million mt produced by China, up 1.2 percent, 24.36 million mt produced by Japan, decreasing by 2.4 percent, 27.5 million mt produced by India, falling by 5.3 percent, and 16.94 million mt produced by South Korea, down by 4.8 percent - with all comparisons on year-on-year basis.
As a bulk commodity, the rise and fall of S460M material, steel pipe prices are related to many downstream industries, such as construction industry, railway, highway, urban public transport and other infrastructure construction, industry and real estate. The price of S460M material, steel pipe rises and falls every day, and is guided by the quotation market in various places. However, in fact, the procurement of steel pipes is more complicated than this, and the market guide price can only be used as a reference.
Pakistan's iron and steel industry has suspended S460M material production and operation since the outbreak, the dawn reported on April 8. Last month, Prime Minister Imran announced a rescue package for the steel industry. Recently, Pakistan's steel industry called for the resumption of production as soon as possible.
