Hot rolled steel coil sheet S690 steel

A36 plates technical parameters, A36 ms steel sheets datasheet: A36 steel consists of carbon 0.25% max., phosphorus 0.040% max., sulphuric 0.050% max., silicon 0.40% max. and copper 0.20% max. Mechanical properties of A36 steel include yield strength 250Mpa min., tensile strength 400-500Mpa and elongation 20% min. Brinell hardness 119-162 HBW, based on the conversion from tensile strength. Modulus of elasticity (Young's modulus): 200 GPa (29×103 ksi). Shear modulus: 79.3 GPa (11.5×103 ksi). The density of S690 steel, A36 plates is 7.85g/cm3.

A few days ago, the relevant person in charge of China National Railway Group Co., Ltd. introduced that since the 18th National Congress of the Communist Party of China, 14 concentrated contiguous poverty-stricken areas, including old and poor, have completed a total of 3.3 trillion yuan in railway infrastructure investment, accounting for 78% of the total railway infrastructure investment; 36,000 kilometers of new lines were put into operation (20,000 kilometers of high-speed rail), accounting for 83% of the new lines put into operation in the country. Up to now, the railway network and 154 trackless stations on the whole road cover about 600 national-level poverty-stricken counties, accounting for 73% of the country's 832 poverty-stricken counties.

We have gradually formed four advantageous products of steel plate, steel pipe, S690 steel, stainless steel and special steel, and established our own processing center to meet the diversified needs of customers. At the same time, we also set up professional environmental protection, baby carriage and other projects. With the professional team and strong background of steel plate, steel pipe, stainless steel and special steel, it will drive the rapid development of other projects.

According to the data released by the world iron and Steel Association, the world pig iron production in March 2020 was 103 million tons, a year-on-year decrease of 3.5%, a year-on-year increase of 1.8% in February, and the overseas pig iron S690 steel production excluding China was 36.309 million tons, a year-on-year decrease of 11%.
