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 S420N material vs a573 gr.65 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.
Different from S420N material vs a573 gr.65 steel, the alloy wear-resistant layer of alloy plate is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium, nickel are also added. The carbides in the metallurgical structure are distributed in a fibrous shape, and the fiber direction is perpendicular to the surface. Carbide microhardness can reach HV1700-2000 and surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperatures, maintain high hardness, and also have good anti-oxidation properties. They are fully used within 500°C.
Advantages of S420N material vs a573 gr.65 steel:1. Steel purity: Wugang can produce high purity molten steel with P 0.010%, S 0.005%, N70ppm, O15ppm, H2ppm, and 20ppm total inclusions in the steel.2. Good toughness and weldability.3. The heat treatment technology: normalizing, quenching, tempering, tempering and other heat treatment processing can be carried out on the steel plate as required.4. Significantly improve the plasticity and impact toughness of steel, and improve the anisotropy of steel.
Management concept: abide by laws, regulations and social norms. To improve the system of management, to carry out activities with high corporate ethics. Mutual respect, unity and harmony, create a "fair, just and open" good working environment for employees. Forge ahead, constantly pursue new technology innovation, create social value, and become a sustainable growth enterprise.
