Compared with carbon steel, low alloy steel has many advantages, such as high strength, good plasticity and toughness, good weldability, good cold and hot pressure processing performance, better corrosion resistance, etc. Due to the increase of A514 grade B quenched and tempered steel metal composition, the yield point of low alloy steel structure is higher than that of ordinary carbon steel, so it is light and suitable for structural parts application. The low alloy steel is one of our main products.
A514 grade B quenched and tempered 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 A514 grade B quenched and tempered 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.
Cleveland cliffs announced on March 13 that it had completed the acquisition of AK A514 grade B quenched and tempered steel steel, foreign media reported In the transaction of holding), shareholders of Cleveland cliffs and AK steel respectively voted on the US billion acquisition agreement at their respective shareholders' meeting to complete the resolutions required for the announcement of acquisition of AK steel A514 grade B quenched and tempered steel at the beginning of the year. The acquisition is Cleveland cliffs' first foray into steel manufacturing.
In September, China's apparent consumption of crude steel was 94.38 million tons, an increase of 15.58 million tons or 19.8% year-on-year. It has exceeded 90 million tons for five consecutive months. From January to September, China's apparent crude steel consumption was 770 million tons, an increase of 63.14 million tons or 8.9% year-on-year. In terms of growth rate, the apparent consumption of hot-rolled sheet and coated sheet (strip) from January to September increased by more than 40% year-on-year, and the growth rates were 42.6% and 42.0% respectively; railway steel and electrical steel strips fell year-on-year, with a decline. They are 12.8% and 1.4% respectively.
