Q355D steel plate machining 

The Q355D steel plate has a high moment of inertia and flexural modulus due to the high-rigidity steel formed by the high-strength plate, especially due to the application requirements that require cold punching after pre-punching, which will form the material surface flatness and material edges Difference in size. Therefore, it is required to add lateral positioning devices to the design of Q355D high-strength structural steel cold-bent hole patterns, rational design of hole patterns, and reasonable arrangement of roll gaps, etc., to ensure that the materials entering each hole pattern are not deviated and eliminated as much as possible. The influence of the difference in the flatness of the Q355D material surface and the size of the material edge on the shape of the subsequent cold forming.

Q355D steel stock

Yesterday, the price of Q355D steel plate fluctuated strongly, and by region, part of East China weakened. The North China and Southwest China strengthened, while the rest of the region remained stable. In addition, the fundamental data is still benign, production is declining, and inventory growth rate is average. Therefore, it is expected that the short-term price of Q355D steel plate will continue to operate with strong shocks.
