The weldability of ASTM A588 structural steel plate is good. It means that under certain process and construction conditions, ASTM A588 structural steel plate can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.
Recently, the price of ASTM A588 structural steel plate raw materials has been strong, the mainstream steel mills have raised the price, and the cost of taking goods by ASTM A588 structural steel plate 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 ASTM A588 structural steel plate steel, and high cost supports the price of ASTM A588 structural steel plate steel, while macro capital also disturbs the market from time to time. In the short term, the market wait-and-see sentiment is strong, ASTM A588 structural steel plate steel prices or continue to fluctuate, the range of rise and fall are limited.
