The factory is located in the central China, with convenient transportation and abundant resources. The main products are various construction steel plates, steel pipes, steel sections, and steel structure processing parts. Used in the Q310NQL2 atmospheric corrosion resistant structural steel manufacture of railway tracks, pressure vessels, boilers, hulls, bridges, various types of steel, etc. With an annual output of 2.23 million tons of steel plates, 2.04 million tons of steel pipes and 1.54 million tons of section steel in 2002, it is an important pig iron base in Henan Province.
Cleveland cliffs announced on March 13 that it had completed the acquisition of AK Q310NQL2 atmospheric corrosion resistant structural 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 Q310NQL2 atmospheric corrosion resistant structural steel at the beginning of the year. The acquisition is Cleveland cliffs' first foray into steel manufacturing.
The company has allocated special environmental protection facilities for all Q310NQL2 atmospheric corrosion resistant structural steel pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, Q310NQL2 atmospheric corrosion resistant structural steel steel mill scale, environmental protection dust has reached 100%.
Generally speaking, the higher the strength of Q310NQL2 atmospheric corrosion resistant structural steel, weathering steel, the greater the hardness, while the plasticity and toughness will decrease. When the carbon content of weathering steel exceeds 1.2%, the hardness will increase, but the strength will not increase, but will decrease. Resilience will also decline quickly. When the carbon content is high, the cementite increases and forms network distribution, which weakens the connection between grains and makes the mechanical properties of steel worse.
