The production process of hot-rolled steel plate and cold-rolled steel plate is different. Hot rolled steel plate is rolled at high temperature, and cold rolled steel plate is rolled at normal temperature. Generally speaking, cold rolled steel plate has better strength and hot rolled steel plate has better ductility. The thickness of SA514 grade Q steel material cold rolling is generally smaller, and that of hot rolling can be larger. The surface quality, appearance and dimension accuracy of cold rolled steel plate are better than that of hot rolled steel plate.

Recently, the price of SA514 grade Q steel material raw materials has been strong, the mainstream steel mills have raised the price, and the cost of taking goods by SA514 grade Q steel material merchants has risen. In addition, macro capital will still have a disturbance to the market, and the current wait-and-see sentiment of downstream and middlemen is strong. On the whole, the steel market is intertwined with many spaces, and the supply and demand fundamentals are generally in a weak balance pattern. High inventory suppresses the price of SA514 grade Q steel material steel, and high cost supports the price of SA514 grade Q steel material steel, while macro capital also disturbs the market from time to time. In the short term, the market wait-and-see sentiment is strong, SA514 grade Q steel material steel prices or continue to fluctuate, the range of rise and fall are limited.
