Generally speaking, rolled plates are easier to handle in a high temperature environment, and the heat treatment of A514 Gr B high strength steel plate, 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.
SM520B plate is Japanese standard low alloy high strength steel plate, which is in accordance with JIS g3101 standard. A514 Gr B high strength steel plate, material SM520B is used for medium and low pressure vessels, oil tanks, vehicles, cranes, mining machinery, power stations, bridges and other structures bearing dynamic loads, mechanical parts, building structures, general metal structural parts. It is supplied in hot rolling or normalizing state, and can be used for various structures in cold areas above - 40℃.
Due to the high cost support of raw material end and the re attack of environmental protection and production restriction of steel enterprises, the market supply is limited and A514 Gr B high strength steel plate traders are willing to support the price. However, the influence of off-season continues, the terminal demand is greatly reduced, and the downstream merchants mainly purchase on rigid demand. The overall delivery performance is not good. It is expected that the A514 Gr B high strength steel plate price will be adjusted steadily tomorrow.
