20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, S450J0 carbon steel plate sheet. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.

S450J0 carbon steel plate sheet, Hot rolled seamless tube is usually produced on automatic tube rolling mill. After the solid tube blank is inspected and the surface defects are removed, it is cut to the required length, centered on the end face of the piercing end of the tube blank, then sent to the heating furnace for heating, and perforated on the piercing machine.

One person familiar with the situation said Germany's ailing ThyssenKrupp Group was in talks with its international counterparts to merge its loss making S450J0 carbon steel plate sheet steel business. The talks will be announced Monday as part of a strategic reform that could include closing or selling assets. Previously, ThyssenKrupp steel Europe, Germany's largest steelmaker, announced a loss in the first half of the group three point seven two 100 million euros four point zero two Billion US dollars). ThyssenKrupp has continued to advocate the benefits of S450J0 carbon steel plate sheet steel integration since it abandoned its joint venture with Tata Steel a year ago to sell its precious elevator division.

For employees' development,  the company's transformation and development provides employees with a broad career development platform. The company needs "lion-type" entrepreneurial leaders who are full of entrepreneurial enthusiasm and dare to self-renovate.

It is reported that during the period from the end of 2018 to the first quarter of 2019, some Japanese long process steel mills encountered a series of production line equipment failures, resulting in the overall output decline. Japanese S450J0 carbon steel plate sheet steel mills must give priority to domestic customers, so the export volume in the first half of last year was relatively small. Meanwhile, in the first half of the year, Japan's imports of general S450J0 carbon steel plate sheet steel were about 2.079 million tons, down 16.4% year-on-year; imports of special steel were about 332000 tons, down 14.2% year-on-year.
