The difference between q345 and q235 steel A709 grade 100 bridge steel plateThe lower limit of yield strength of Q345 is 345MPa (the actual meaning of Q is the Chinese character "qu", and the standard value behind means the lower limit of yield strength). Q235 steel is used for metal structural parts, nitrided or cyanidized parts with low core compressive strength requirements, support rods, crankshafts, crane hooks, couplers, bolts and nuts, sleeve specifications, shafts and weldments.
It can be predicted that in 2019, the national steel market quotation will not appear unilateral quotation, rebar A709 grade 100 bridge steel plate steel main contract price of the largest shock range (the lowest price to the highest price), it is possible to reach as much as 1000 yuan this is the New Year's Chinese steel market quotation of the first characteristic. The second characteristic of Chinese steel market quotation in 2019 is that the average A709 grade 100 bridge steel plate steel price of the whole year is roughly flat with the level of the previous year, or it is to rise somewhat, generally there will be no annual average price decline.
What is the the price of A709 grade 100 bridge steel plate inventory? EXW price: 532 USD per ton 11*2080*13550, 11.5*2770*8470, 12*1650*7800, 10*2240*8875, 14*3545*5070,, 10*2050*7900, 10*1800*7800, 14.5*2250*10280, 12*3570*13100, 10*3690*10170, 15*2550*6650, 12.5*2415*8550, 15*3200*15000, 12.5*2030*13450, 13*3340*10900, 12*1560*8725, 13*3200*15000, 14*3700*11040, 9*3500*6750, 12*2720*8725, 15*1620*4000, 15*3920*8620, 13*3055*11550, 13*2230*15150."
In recent years, after the completion of large-scale, high-speed and automation of steel rolling technology and equipment in the world, the rapid development of A709 grade 100 bridge steel plate high-precision rolling technology with the goal of improving product quality, expanding varieties, saving energy and reducing consumption, and increasing benefits. For example, in 2013, Bebon Iron and Steel's 4300 mm rolling mill, 5000 mm rolling mill and 3500 mm furnace coil rolling mill introduced foreign technology to further upgrade the company's A709 grade 100 bridge steel plate technical equipment.
