In the second step of hot rolling process, different finished mills are used to roll billets or continuous casting billets into finished steel of proper shape and size. This A514 Gr E structural steel material production process is called finished product production, which is generally divided into two stages of rough rolling and finish rolling. In the roughing stage, a large amount of reduction (reduction per pass) is adopted to reduce the number of passes and improve the output; after roughing, the finishing stage is entered, and the finishing is carried out with a small amount of reduction to achieve a good surface and accurate A514 Gr E structural steel material size.
One person familiar with the situation said Germany's ailing ThyssenKrupp Group was in talks with its international counterparts to merge its loss making A514 Gr E structural steel material 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 A514 Gr E structural steel material steel integration since it abandoned its joint venture with Tata Steel a year ago to sell its precious elevator division.
Both 20# seamless steel pipe and 20G seamless steel pipe are carbon structural steel with average carbon content of 0.20%. There are big differences in the use standard, chemical composition, mechanical properties and price between A514 Gr E structural steel material, 20# seamless steel pipe and 20G seamless steel pipe, so they must be selected correctly in the design and use, so as to avoid affecting the service life or even causing destructive accidents. The purpose of A514 Gr E structural steel material, GB8162 20# seamless steel pipe is for general structure, the purpose of GB8163 20# seamless steel pipe is for conveying fluid, and the purpose of GB3087 standard 20# seamless steel pipe is for low and medium pressure boiler. 20G seamless steel pipe is used for high pressure steam boiler and pipeline.
The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable A514 Gr E structural steel material steel products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the market and has strong competitiveness.
