One person familiar with the situation said Germany's ailing ThyssenKrupp Group was in talks with its international counterparts to merge its loss making A573 grade 58 CS steel carbon plate 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 A573 grade 58 CS steel carbon plate steel integration since it abandoned its joint venture with Tata Steel a year ago to sell its precious elevator division.
The density of wear-resistant plate is higher than that of some materials, A573 grade 58 CS steel carbon plate, which makes its hardness larger. The density of steel for wear-resistant plate is 7.85kg/dm cubic. After quenching, martensite structure is obtained and tempered at 450-600℃, or 350-600℃ after tempering at 650℃. Or after tempering at 650℃ and heating at 350-650℃ for a long time, the wear-resistant plate will be embrittled. If the brittle wear-resistant plate is reheated to 650℃ and then cooled quickly, the toughness can be restored, so it is also called reversible temper brittleness. High temperature temper brittleness is the increase of the transition temperature from toughness to brittleness.
A573 grade 58 CS steel carbon plate, 12Cr1MoV steel is alloy structure steels, and it is usually produced into 12Cr1MoV steel coil, 12Cr1MoV steel sheet, 12Cr1MoV steel plate, 12Cr1MoV steel bar, etc. 12Cr1MoV steel is composed of Carbon, Silicon, Manganese, Chrome, Molybdenum and so on chemical elements. Amng them, the C content is 0.08-0.15, Si 0.17-0.37, Mn 0.40-0.70, Cr 0.90-1.20, Mo 0.25-0.35. The tensile strength of 12Cr1MoV steel is not lower than 490 Mpa, and yield strength is not lower than 245 Mpa.
