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. SPA-C plate wholesale, 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.After a certain period of time, the steel products will reduce the toughness and increase the hardness, which is called aging effect. Generally, this effect is strongest at 200-300 ℃. The aging tendency of SPA-C plate wholesale, low carbon steel (about 0.1% carbon content) is especially large, while high carbon steel and alloy steel containing molybdenum, barium or tungsten are not easy to produce aging. For boiler steel plate, it is required that the reduction rate of impact initial property is not more than 50%, or the absolute value of impact initial property is not less than 3-3.5KGM / cm2.According to the economic development trend in Asia and the economic development of China, India, Japan and ASEAN, it is estimated that the steel consumption in Asia will be 1228 million tons in 2019, with a year-on-year growth of 6.6%; the SPA-C plate wholesale steel demand in Asia in 2020 is predicted to be 1.241 billion tons, with a year-on-year growth of 1.1%. According to the SPA-C plate wholesale economic development of Europe, it is estimated that the steel consumption in Europe will be 202 million tons in 2019, with a year-on-year decrease of 3.3%; the steel demand in Europe in 2020 is predicted to be 205 million tons, with a year-on-year growth of 1.5%.In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.This week, the output of SPA-C plate wholesale increased slightly, while the total inventory changed from decrease to increase, indicating that the apparent consumption of SPA-C plate wholesale decreased again. At present, due to the current demand release is not as expected, while the SPA-C plate wholesale production and inventory are still at a relatively high level, the market wait-and-see sentiment is strong. To sum up, it is expected that SPA-C plate wholesale prices will continue to narrow consolidation in the short term.
