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 A709 grade 50W high strength steel 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. In the three months to March 31, Hyundai Steel had a net loss of 88.6 billion won ( million), up from 94.4 trillion won in net profit in the same period last year.

Low-alloy structural steel plates are mainly used in machinery manufacturing and metal structural parts. Advantages of A709 grade 50W high strength steel, low-alloy structural steel plates: They have superior performance and light weight. Disadvantages of low-alloy structural steel plates: These steel plates are all killed plates. The molten steel is deoxidized before the production. When the molten steel is poured into the ingot mold, its reaction is relatively calm and there will be no boiling state. A709 grade 50W high strength steel, low-alloy structural steel plates price will be more expensive.
