Tensile requirement of 09cupcrni-a steel demand

Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements. It has the characteristics of high-quality steel, such as strength, toughness, ductility, forming, welding and cutting, abrasion, high temperature, fatigue and so on. The weathering resistance of weathering steel is 2-8 times of that of plain carbon steel 09cupcrni-a steel demand, and the coating property is 1.5-10 times of that of plain carbon steel. Weathering steel has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving, etc..

In recent years, after the completion of large-scale, high-speed and automation of steel rolling technology and equipment in the world, the rapid development of 09cupcrni-a steel demand high-precision rolling technology with the goal of improving product quality, expanding varieties, saving energy and reducing consumption, and increasing benefits. For example, in 2013, Bebon Iron and Steel's 4300 mm rolling mill, 5000 mm rolling mill and 3500 mm furnace coil rolling mill introduced foreign technology to further upgrade the company's 09cupcrni-a steel demand technical equipment.

Sulfur is a very harmful element in 09cupcrni-a steel demand steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of 09cupcrni-a steel demand steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.

According to the data released by the Japan iron and Steel Union (JISF), the export volume of Japanese steel in the second quarter of 2020 09cupcrni-a steel demand is about 4.959 million tons, a year-on-year decrease of 14.2%; the export volume in the first half of 2020 is about 11.07 million tons, with a year-on-year growth of 1.8%. It has been revealed that the year-on-year increase in export volume does not mean that Japan's export 09cupcrni-a steel demand situation of Pugang is better in the first half of the year, but only because the base number of the same period last year is too low.
