200 * 1000mm A572 Gr 50 carbon steel plate sheet with low price

A572 Gr 50 carbon steel plate sheet, Q890E steel plate is a kind of quenched and tempered steel plate for high strength structure, in which "Q" means yield, "890" means yield value, "E" means grade level. Q890E steel is equivalent to EN grade S890QL.Executive standard of Q890E steel plate: GB / T 16270.Q890E steel plate delivery status (heat treatment): quenching and tempering.The size, shape, weight and allowable deviation of Q890E steel plate shall comply with GB / T709.

Today, the trend of black futures remained high, and the spot market price continued to rise. However, after the rise, the overall turnover of the market weakened compared with the previous trading day, and the transaction of low-cost resources was acceptable. In terms of steel mills, the output of steel mills continues to be high, with firm ex factory prices and relatively saturated orders. A572 Gr 50 carbon steel plate sheet traders are reluctant to sell at a low price due to the high cost of taking goods, which will support the A572 Gr 50 carbon steel plate sheet price in the short term. It is expected that A572 Gr 50 carbon steel plate sheet prices will maintain a high consolidation trend tomorrow.

High-strength steel plates have the following characteristics. First, the strength is high, the bearing capacity is very good, and it is not easy to break. Second, compared with other steel plates under the same strength requirements, high-strength steel plates are lighter and thinner, which can effectively reduce the weight of structures. Third, the A572 Gr 50 carbon steel plate sheet, high-strength steel plates are required to be safe and reliable, able to withstand complete disasters such as water, fire, earthquake, storm, etc., to protect people's safety.

A572 Gr 50 carbon steel plate sheet surface cracks refer to the linear cracks on the surface of A572 Gr 50 carbon steel plate sheet, which should generally be the same as the forging or rolling direction. Formation reason: it is mainly due to the hairline, hot crack and cold crack caused by surface over burning, decarburization, looseness, deformation and excessive internal stress during processing (forging, rolling, heat treatment, quenching and tempering), as well as the high content of sulfur and phosphorus impurities on the surface. Inspection method: A572 Gr 50 carbon steel plate sheet surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.
