SA709 Gr.50 sheet size, Q235 carbon content: 0.14-0.22%; Tensile strength (σb/MPa): 375-500. Q235 steel is usually rolled into coil bar or round steel, square steel, flat steel, angle steel, I-beam, channel steel, window frame steel and other section steel, medium and thick steel plate. Q235 steel is used for making steel bars or building plant house frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc.
Turkey produced 8.97 million metric tons of crude steel in the first quarter, with a 9.6 percent increase from the same month of last year. Iran's crude SA709 Gr.50 sheet size steel production in March amounted to 6.75 million mt. up by 13.2 percent year on year. The CIS registered a SA709 Gr.50 sheet size crude steel output of 25.15 million mt. falling by 0.6 on year-on-year basis, with Russia producing 17.9 million mt, down by one percent, and Ukraine producing 5.32 million mt, falling by 3.4 percent, both on year-on-year basis.
Steel strip is a branch of steel plate. Steel strip is a kind of narrow and long steel plate, also known as strip steel, SA709 Gr.50 sheet size produced by various steel rolling enterprises to meet the needs of different industrial departments and industrial production of various metal or mechanical products. The width of steel strip is within 1300mm, and the length is slightly different according to the size of each roll. Generally, SA709 Gr.50 sheet size steel strip is supplied in coils, with the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. The steel strip is a kind of steel with large output, wide use and many varieties.
The steel plate and strip after hot rolling treatment are generally called hot rolled plate. Compared with other steel plate processing industries, SA709 Gr.50 sheet size, hot rolled plate has these characteristics. First, low hardness, easy processing. Compared with other steel needs special mechanical equipment, hot rolled plate is a very convenient for processing. Second, good ductility, not easy to break, good compression capacity, long service life. Third, the manufacturing process is simple, and the price and cost are relatively cheap compared with other steels.
