The company attaches great importance to the value of iron and steel, constantly improving itself in terms of attitude, innovation, human resources, etc., integrating the value of iron and steel into the company's philosophy, showing the spirit of fighting for A572 grade 50 ms steel coil iron and steel, forging iron and steel enterprise, creating steel market, establishing iron and steel team, and attaching importance to the sustainable development of iron and steel industry, so as to make iron and steel our permanent cause.
The yield strength of A572 grade 50 ms steel coil, Q235 steel plate decreases with the increase of thickness. Q235 steel plate thickness≤16mm, yield strength is 235MPA; 16mm < Q235 steel plate thickness≤40mm, yield strength is 225MPA; 40mm < Q235 steel plate thickness≤60mm, yield strength is 215MPA; 60mm < Q235 steel plate thickness≤100mm, yield strength is 205MPA; 100mm < Q235 steel plate thickness≤150mm, yield strength is 195MPA; 150mm < Q235 steel plate thickness≤200mm, yield strength is 185MPA.
After a certain period of time, the steel products will reduce the toughness and increase the hardness, which is called aging effect. Generally, this effect is strongest at 200-300 ℃. The aging tendency of A572 grade 50 ms steel coil, low carbon steel (about 0.1% carbon content) is especially large, while high carbon steel and alloy steel containing molybdenum, barium or tungsten are not easy to produce aging. For boiler steel plate, it is required that the reduction rate of impact initial property is not more than 50%, or the absolute value of impact initial property is not less than 3-3.5KGM / cm2.
Turkey produced 8.97 million metric tons of crude steel in the first quarter, with a 9.6 percent increase from the same month of last year. Iran's crude A572 grade 50 ms steel coil steel production in March amounted to 6.75 million mt. up by 13.2 percent year on year. The CIS registered a A572 grade 50 ms steel coil crude steel output of 25.15 million mt. falling by 0.6 on year-on-year basis, with Russia producing 17.9 million mt, down by one percent, and Ukraine producing 5.32 million mt, falling by 3.4 percent, both on year-on-year basis.
The company has an entrepreneurial team composed of highly educated and high-quality talents, whose leaders graduated from famous universities. As the first group of teams engaged in e-commerce industry in China, it witnessed the rapid development of e-commerce, accumulated rich steel professional knowledge and formed a scientific management system.
In terms of inventory, the recent arrival of new A572 grade 50 ms steel coil resources is relatively small. Due to the high ordering cost, the weakening of merchants' purchasing enthusiasm, and the rapid production of steel mills, resulting in the shortage of some A572 grade 50 ms steel coil specifications. On the whole, the market has a strong wait-and-see mood. The ex factory prices of steel mills are strong and some resources are in short supply. It is expected that A572 grade 50 ms steel coil prices will continue the high consolidation operation tomorrow.
