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 A573 Gr 70 carbon steel sheet 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.
The strength level of traditional spring steel is difficult to meet the requirements of modern industrial development. As we all know, the mechanical properties of A573 Gr 70 carbon steel sheet, spring steel depend on the heat treatment process under the premise of material quality assurance, and the heat treatment process should also be determined according to the material itself. An important way to increase the strength of spring steel is to give full play to the role of alloying elements to achieve the best alloying effect.
ASTM a588 is a high strength low alloy HSLA steel (high strength, low alloy) containing a small amount of alloying elements copper, chromium and AMP. Nickel. These alloying elements effectively improve the properties of a588 and expand its application range. Firstly, the alloy composition increases the A573 Gr 70 carbon steel sheet yield point strength to 50 Ksi and the tensile strength to 70 Ksi. Secondly, a588 A573 Gr 70 carbon steel sheet has high copper content, atmospheric corrosion resistance and long working time. Because of its excellent comprehensive performance, a588 angle steel is widely used in bridge, building and other structural fields.
