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 150mm GL-DH 36 TM rolled 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.
Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;
In October, 2018, our Malaysia customer purchased 600 Tons CCS-AH36 Ship Building Steel Plates to use in their shipbuilding project .This customer is a famous shipyard in Malaysia. Their company has the business scope of tourism, 150mm GL-DH 36 TM rolled steel shipbuilding, transportation and so on. As a terminal manufacturer, they have strict requirements on quality . After visiting our factory, the customer are very satisfied with the quality of this batch of 150mm GL-DH 36 TM rolled steel CCS-AH36 Ship Building Steel Plates.
Primary processing, steel plate cutting processing cutting method, it is a flame cutting, because it to the accuracy requirement of the cutting size is not very high, the thickness of the 150mm GL-DH 36 TM rolled steel plates in a certain range can be a good cutting quality and cutting effect, and the cut surface can be very smooth, however, it is important to note that in this work, is the need to pay attention to steel plate deformation at high temperature.
Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This 150mm GL-DH 36 TM rolled steel alloy steel 150mm GL-DH 36 TM rolled steel still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.
Insist on the spirit of development and indomitable entrepreneurship; the spirit of leading science and technology and striving for first-class affairs; the spirit of strict management and market development; the spirit of taking the lead in setting an example and selfless dedication; and the spirit of people-oriented and enterprise ownership.
