Q235D carbon steel plate sheet sheet chemical analysis

Q420q material is a kind of structural steel plate for bridges, and there are three quality levels Q420qD, Q420qE and Q420qF. When the Q420q plate is required to have the performance in the thickness direction, the symbols Z15, Z25, Z35 representing the performance level in the thickness direction are added after the above-mentioned grades. Namely Q420qDZ15, Q420qDZ25, Q420qDZ35, Q420qEZ15, Q420qEZ25, Q420qEZ35, Q420qFZ15, Q420qFZ25, Q420qFZ35.

The "Plan" pointed out that by the end of December 2020, the steel production capacity in Tianjin will be controlled at about 15 million tons, and the steel production capacity in Hebei Province will be controlled within 200 million tons, and the elimination of the carbonization chamber with long furnace age and poor furnace condition will be accelerated. 4.3 Rice coke ovens promote the gradual withdrawal of independent coking companies. At present, there are 24 steel enterprises in Shanxi Province in need of transformation, of which 17 have been completed, and the remaining 7 enterprises are speeding up project-related finishing work.

EXW price: 532 USD per ton11*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."

As the thickness and hardness of Q235D carbon steel plate sheet increase, the tendency to crack at the cutting edge increases. In order to prevent the Q235D carbon steel plate sheet from cutting cracks, preheating should be carried out before Q235D carbon steel plate sheet cutting. Special attention should be paid to preheating to make the entire Q235D carbon steel plate sheet interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole Q235D carbon steel plate sheet cannot be preheated, the partial preheating method can be used instead.
