The ASTM A242 coil density data from BBN

Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to their different materials and properties. According to the different uses, ASTM A242 coil it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, welding gas cylinder steel and pressure vessel steel, pipeline steel, etc.

A709GR50 steel plates are used in construction steel structure, construction machinery and other steel structures, such as construction steel structure, construction machinery, mining and mountain machinery, heavy trucks, bridges, pressure vessels, etc., especially for requirements with better weldability And tough construction and construction machinery parts. The product ASTM A242 coil has been exported to South Korea, Taiwan and other places, and the cumulative export volume has reached more than 10,000 tons.

The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube, ASTM A242 coil tube.

South Korean ASTM A242 coil steel industry said that the slowdown in economic growth superimposed on the impact of the epidemic, steel demand weakened, exports were sluggish, enterprises are facing huge operating pressure. Due to the delay in the resumption of work of Chinese ASTM A242 coil steel enterprises, the steel inventory is growing rapidly. According to statistics, China's steel circulation inventory reached 23.75 million tons in February, the highest since 2006, with an estimated total inventory of 33.45 million tons.
