Generally speaking, rolled plates are easier to handle in a high temperature environment, and the heat treatment of A283 grade D mild steel coil, rolled plates is also very common. Hot rolling can not only greatly reduce energy consumption and save costs, but also improve the processing performance of metals and alloys, that is, the coarse grains in the as-cast state are broken, the cracks are healed significantly, and the processing performance of the alloy is improved.
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 main competitive means adopted by major domestic ports are to expand ports, build deep-water berths and channels, improve service quality to reduce the comprehensive cost of customers, and at the same time, to improve competitive advantage, we should also take appropriate measures to reduce relevant costs and prices.
