What are the raw materials for making 1.8940 steel

1.8940 steel 2020 stock in Shanghai: 25*1600*9300, 23.1*2590*7790, 25*1600*9300, 25*1600*9500, 14*1950*10800, 25*1600*9500, 20*1400*11400, 30*1600*8600, 30*2000*10200, 14*1950*10950, 25*1600*9300, 30*1600*8600, 9*2300*6870, 35*2500*9000, 9*2300*6870, 25*1600*9500, 9*2300*6870, 6*2000*10000, 20*1640*11250, 70*2270*7900, 6*2000*10000, 30*1600*8600.

1.8940 steel and so on steel structure engineering steel has good plasticity, which can make the structure have obvious deformation before being destroyed, so as to avoid brittle failure of structure. The good plasticity of steel can adjust the local peak stress to redistribute the stress, and improve the ductility of components, so as to improve the seismic capacity of the structure. The impact toughness of 1.8940 steel and so on steel structure engineering steel is good, which can improve the ability of resisting dynamic load and avoid the occurrence of cracks and brittle fracture.

The Brazil steel is facing a "crisis of demand" as the epidemic of new crown pneumonia spreads in Brazil. The demand for 1.8940 steel and so on steel will be reduced by 50% in April. The demand for the second quarter will be 40% lower than that in the first quarter. The demand for this year will be reduced by 20% compared with the same period this year. In 2019, Brazil's apparent steel consumption was 20.6 million tons, a year-on-year decrease of 2.7%; crude steel production dropped to 32.33 million tons, the lowest since 2016 (30.2 million tons).

The fake and inferior 1.8940 steel, steel plates have no metallic luster and are light red or similar to pig iron for two reasons. 1. Its blank is adobe. 2. The rolling temperature of counterfeit and inferior materials is not standard, and their steel temperature is visually inspected. In this way, rolling cannot be carried out in the specified austenite area, and the performance of the steel plate will naturally not meet the standard.
