The overall intention of supporting prices in the raw material market is relatively strong, but the steel mills have a low acceptance of high prices, and some just need a small amount of goods, so the overall market game state is obvious. With the poor release of steel demand, terminal merchants tend to consume low-cost inventory in the early stage and purchase on demand to avoid the risk of large-scale hoarding. However, the cost side is weak, and some A514 grade E structural steel material manufacturers secretly reduce prices to promote transactions. It is expected that the A514 grade E structural steel material market will be stable and weak in the future.
After heating, a billet is refined for several passes of rolling, then edge cutting and straightening to become a A514 grade E structural steel material steel plate, which is called hot rolling. Due to its high strength, good toughness, easy processing, good weldability and other excellent properties, hot rolled steel plate products are widely used in shipbuilding, automobile, bridge, construction, machinery, pressure vessel and other manufacturing industries.
Hyundai Steel Co. has no plans to cut production further despite weak steel demand due to the coronavirus pandemic, the company's president said. Earlier this year, South Korea's second largest steelmaker reduced its A514 grade E structural steel material annual production of hot rolled coils from 1 million tons previously to 700 thousand tons per year for EAFs. A turnaround is expected after the third quarter of this year.
