How to prevent cracks in EN10025-4 S420ML steel plate cutting

What should be paid attention to when using EN10025-4 S420ML steel plate, carbon steel? First, the strength level of carbon steel is low and it is easy to fracture, so carbon steel is not suitable for high strength engineering. Second, the heat-resistant performance of carbon steel is relatively poor, which can not be applied in the long-term high-temperature fields such as boilers. Third, the carbon steel is extremely easy to rust, so it is not suitable for water transport projects. Therefore, the use of carbon steel depends on the use of the environment, if it is harsh conditions, it is better to choose other steel materials.

Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with EN10025-4 S420ML steel plate ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.

One person familiar with the situation said Germany's ailing ThyssenKrupp Group was in talks with its international counterparts to merge its loss making EN10025-4 S420ML steel 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 EN10025-4 S420ML steel plate steel integration since it abandoned its joint venture with Tata Steel a year ago to sell its precious elevator division.
