S275 material Comparison

The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as S275 material, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.

Tokyo (Reuters) - Japan's crude steel production is expected to fall 25.9% in the April June quarter from a year earlier, the Ministry of economy, trade and industry said on Thursday. The Ministry of economy and industry quoted an industry survey report as saying that the demand for steel products (including export products) in April June is expected to drop 18.1% to 18.28 million tons from the same period last year. At the same time, S275 material and so on steel exports in the current quarter will decline by 21.4% year-on-year.

SM490A steel plate is a low-alloy high-strength steel. It is a structural steel produced in accordance with Japanese standard JIS G3106. Its strength σb is 490MPa. It is mainly used for buildings, bridges, ships, rail vehicles, petroleum storage tanks, containers and other buildings that require advanced weldability. S275 material, JIS SM490A steel sheet delivery status: steel plates with a thickness of ＜80mm, the delivery state is hot-rolled; steel plates with a thickness of ≥80mm, the delivery state is normalized condition.
